Left-to-right evaluation: 13-2=11, 11*7=77, 77-9=68, 68-2=66. The no-precedence rule was explicit so no ambiguity.

8 km = 8000 m, then 8000 km = 8,000,000 m. Simple two-step unit trick, easy.
format-json-1✓ pass5s
prompt
Reply with ONLY a JSON object, no other text. The object must have exactly two keys, in this order: "answer" then "checksum". "answer" must be the string "9372". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 9372. Example shape: {"answer":"1234","checksum":10}

The smallest row fooled my first read (I initially saw CZY68), but a 10x crop showed the last two glyphs are clearly E and R, giving CZYER. This one is genuinely borderline at native resolution; the crop decided it.

My first eyeball count said 15 blue diamonds, but a pixel-level connected-component analysis with shape classification found 14 blue diamonds plus 2 blue triangles, 1 blue circle and 1 blue square. The crop-based recount by rows (2+5+2+4+1) agreed with the program. I trust 14.

Pixel analysis found exactly 25 blue (royal blue) square components; the image is busy enough that I would not trust an eyeball count. Main risk is a merged/occluded shape, but sizes looked uniform.

Traced the arrow programmatically: 7 arrows, and the one with its tail at the blue square has its arrowhead at the blue circle. Matches my visual read. One subtlety: another arrow points AT the blue square (from the purple diamond), so direction mattered.

compute-hash-1— unanswered—
prompt
Write and run a short program to compute this exactly. Use unsigned 32-bit arithmetic modulo 2^32 throughout. Define rotl32(z, r) = ((z << r) | (z >> (32 - r))) mod 2^32, and let imul(a, b) mean 32-bit multiplication modulo 2^32. Start with data = [3945505416, 2807961129, 1151669374, 884449815, 4034760900, 3036852373, 4106089690, 2056396067, 1181659712, 968517441, 1290219126, 662737519], x = 1145185020, y = 2431780397 and rounds = 25000. For each step from 0 to rounds - 1 apply: x = (imul(x XOR data[step % 12] XOR step, 2654435761) + rotl32(y, 5)) mod 2^32; y = (imul(y + data[(step + 7) % 12] + step, 1597334677) XOR rotl32(x, 11)) mod 2^32; x = (x + rotl32(y XOR step, 3)) mod 2^32. Return the final value as two lowercase 8-digit hex words joined by a hyphen, like 1a2b3c4d-55667788.

Write and run a program to execute this tiny machine exactly. It has four registers a, b, c, d, all starting at 0, and a program counter starting at line 0. `set r n` sets r to n. `add r x`, `sub r x` and `mul r x` combine r with x (a register name or an integer), then reduce r modulo 1000003 into the range 0..1000002. `dec r` subtracts 1 from r. `jnz r k` jumps k lines (relative; k may be negative) if r is not 0. `halt` stops. Every other instruction moves to the next line. 0: set a 15 1: set b 616 2: set c 352 3: set d 412 4: sub a 69 5: add a b 6: mul b 52 7: dec d 8: jnz d -4 9: add b a 10: dec c 11: jnz c -8 12: halt Respond with just the final value of register a.

Our shipping quote function below has one bug. Bug report: this order is quoted 2486 cents, but the correct quote is 1140: {"country":"JP","items":[{"grams":1172,"qty":1,"price":17200,"fragile":false}]} Fix the bug without changing any other behaviour, then run the fixed quote() on each of the 20 orders below, in order. Respond with just the 20 results separated by commas. const ZONES = { FR: 1, DE: 1, ES: 1, IT: 1, GB: 2, US: 2, CA: 2, JP: 3, BR: 3, AU: 3 }; // any other country is zone 4 const BASE = [0, 405, 845, 1346, 1761]; // cents, by zone const PER_STEP = [0, 86, 118, 228, 279]; // cents per 250 g step, by zone const FREE_BASE_OVER = [0, 4100, 8200, 17200, Infinity]; // order value (cents) that waives the base fee function quote(order) { const zone = ZONES[order.country] ?? 4; let grams = 0; let value = 0; let fragile = 0; for (const item of order.items) { grams += item.grams * item.qty; value += item.price * item.qty; if (item.fragile) fragile += item.qty; } const steps = Math.max(1, Math.ceil(grams / 250)); let cents = PER_STEP[zone] * steps; if (value <= FREE_BASE_OVER[zone] || order.express) cents += BASE[zone]; cents += Math.min(fragile, 3) * (120 + 35 * zone); if (order.express) cents = Math.ceil((cents * (zone <= 2 ? 150 : 185)) / 100); if (order.coupon === "SHIP10") cents -= Math.min(cents >> 3, 500); return Math.max(cents, 99); } Orders: {"country":"AU","items":[{"grams":1349,"qty":1,"price":17200,"fragile":false}]} {"country":"ES","items":[{"grams":1348,"qty":1,"price":894,"fragile":false},{"grams":168,"qty":5,"price":5139,"fragile":true},{"grams":901,"qty":2,"price":3050,"fragile":false}]} {"country":"US","items":[{"grams":618,"qty":4,"price":7950,"fragile":true},{"grams":1259,"qty":4,"price":1984,"fragile":true}],"express":true,"coupon":"SHIP10"} {"country":"IT","items":[{"grams":1509,"qty":3,"price":6292,"fragile":false},{"grams":1538,"qty":3,"price":3708,"fragile":false},{"grams":1395,"qty":3,"price":3510,"fragile":true},{"grams":759,"qty":2,"price":1362,"fragile":true}],"coupon":"SHIP10"} {"country":"FR","items":[{"grams":590,"qty":1,"price":4100,"fragile":false}]} {"country":"AU","items":[{"grams":240,"qty":1,"price":7068,"fragile":false},{"grams":1461,"qty":5,"price":2957,"fragile":false},{"grams":250,"qty":1,"price":5806,"fragile":false},{"grams":266,"qty":3,"price":1973,"fragile":false}],"coupon":"SHIP10"} {"country":"AU","items":[{"grams":1456,"qty":4,"price":7140,"fragile":false},{"grams":84,"qty":4,"price":5654,"fragile":false},{"grams":162,"qty":1,"price":4647,"fragile":true},{"grams":457,"qty":3,"price":4902,"fragile":true}]} {"country":"GB","items":[{"grams":432,"qty":1,"price":8200,"fragile":false}]} {"country":"US","items":[{"grams":101,"qty":1,"price":8200,"fragile":false}]} {"country":"DE","items":[{"grams":426,"qty":1,"price":4100,"fragile":false}]} {"country":"FR","items":[{"grams":1046,"qty":1,"price":5947,"fragile":false},{"grams":732,"qty":4,"price":470,"fragile":false},{"grams":319,"qty":2,"price":4040,"fragile":false}]} {"country":"MX","items":[{"grams":419,"qty":1,"price":6244,"fragile":false},{"grams":1598,"qty":2,"price":401,"fragile":false},{"grams":910,"qty":1,"price":4164,"fragile":true}],"express":true} {"country":"AU","items":[{"grams":856,"qty":4,"price":2665,"fragile":false},{"grams":1376,"qty":3,"price":2833,"fragile":false},{"grams":225,"qty":2,"price":4894,"fragile":false}]} {"country":"ZA","items":[{"grams":141,"qty":5,"price":8962,"fragile":false},{"grams":1409,"qty":3,"price":5330,"fragile":false}],"express":true} {"country":"US","items":[{"grams":1106,"qty":1,"price":8200,"fragile":false}]} {"country":"MX","items":[{"grams":1695,"qty":5,"price":4598,"fragile":false},{"grams":291,"qty":1,"price":4597,"fragile":false},{"grams":967,"qty":4,"price":7099,"fragile":false}]} {"country":"GB","items":[{"grams":311,"qty":4,"price":8254,"fragile":false},{"grams":1286,"qty":3,"price":2462,"fragile":false},{"grams":821,"qty":4,"price":3880,"fragile":true}],"coupon":"SHIP10"} {"country":"US","items":[{"grams":1653,"qty":4,"price":5081,"fragile":false},{"grams":894,"qty":2,"price":1887,"fragile":true},{"grams":1108,"qty":3,"price":4878,"fragile":false}]} {"country":"DE","items":[{"grams":1914,"qty":1,"price":4100,"fragile":false}]} {"country":"ZA","items":[{"grams":1582,"qty":3,"price":5304,"fragile":false},{"grams":936,"qty":1,"price":7984,"fragile":false},{"grams":906,"qty":1,"price":7478,"fragile":false},{"grams":1768,"qty":4,"price":8716,"fragile":true}],"express":true}

Write a function mergeIntervals(intervals). Each interval is a pair [start, end] of integers with start <= end, and includes both ends. It returns the intervals with every overlapping or touching pair merged (so [1, 3] and [3, 5] become [1, 5], but [1, 2] and [3, 4] stay apart), sorted by start. The input may be in any order. Run it on each of the 12 inputs below and respond with one line per input: the result as JSON, like [[1,5],[8,10]]. Spaces are ignored. [] [[1,3],[3,5]] [[1,2],[3,4]] [[5,9],[1,10]] [[38,43],[18,23],[0,7],[39,47],[7,10],[19,25],[15,20],[4,5]] [[21,22],[23,29],[2,2],[15,22],[26,28],[27,29]] [[23,27],[19,23],[5,8],[35,36],[10,10]] [[3,3],[28,36],[25,25],[26,33],[19,25],[4,9],[11,18],[7,13]] [[24,30],[26,28],[21,21],[29,31],[5,7]] [[9,13],[1,1],[19,23],[17,17],[36,44],[27,34],[34,40],[28,33]] [[5,11],[35,38],[4,5],[19,21],[20,27],[15,19]] [[36,42],[9,9],[5,7],[1,4],[35,37],[7,9]]
