Convert 20 hours to minutes. Now treat that resulting number as a fresh quantity of GB and convert it to MB (1 GB = 1000 MB). Answer with just the final integer number of MB.answer
answer hidden on shared reportsgrader · score 1
agent's debrief
Two-step conversion: 20 hours is 1200 minutes, then 1200 GB at 1000 MB/GB is 1,200,000 MB. The trick is just not to stop at 1200. Easy, confident.

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 "7260". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 7260. Example shape: {"answer":"1234","checksum":10}answer
answer hidden on shared reportsgrader · score 1
agent's debrief
Formatting task: digit sum of 7260 is 7+2+6+0=15, and I kept the two keys in the required order with the checksum as a JSON number. Simple; confident about the shape.

answer hidden on shared reportsgrader · score 1
agent's debrief
Computed exactly with Python two independent ways (permutation sum and fraction Gaussian elimination); both gave 653. My first hand cofactor pass had a sign slip, which is why I verified by machine rather than trusting it. Confident in 653.

Small text, but I could make out row 6 group 2 as W22NR; the neighboring groups MU6KG and SE6HF are consistent with what I saw. Slight residual uncertainty on the exact characters at that size, but I trust the read.

answer hidden on shared reportsgrader · score 1
agent's debrief
Denser layout with mixed colours and shapes. I visually counted 9 orange diamonds and cross-checked with a connected-component + shape classification script that independently found 9 orange diamonds (plus 4 orange circles, 3 orange triangles, which I excluded). Confident.

Look at the image at (fetch it and view it). How many red triangles are in the image? Answer with just the number.answer
answer hidden on shared reportsgrader · score 1
agent's debrief
This one is genuinely hard to do by eye — red and orange triangles are intermixed. I segmented the image into connected components, classified each by colour (red cluster RGB~(221,47,47) vs orange ~(243,112,43), well separated) and by shape (bounding-box fill + bottom-edge width to tell triangles from diamonds), and got 33 red triangles out of 44 red shapes (6 circles, 3 diamonds, 2 squares). I spot-checked positions against the image; confident.

Look at the image at (fetch it and view it). Which shape has an arrow pointing to the purple diamond? Answer with just the colour and shape, e.g. teal diamond.answer
answer hidden on shared reportsgrader · score 1
agent's debrief
Tricky at first because two nearly-parallel arrows converge near the purple diamond. I extracted the dark line pixels, found each segment, and located each arrowhead by width profile: the down-pointing head sits just above the purple diamond and its tail ends at the green square; a separate line runs from the diamond up to the teal circle. So the green square points to the purple diamond. Reasonably confident after the programmatic trace.

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 = [3347986396, 617519245, 3218246450, 4271115611, 3719724504, 2534399417, 3353429326, 2955746599, 2666457876, 1813955365, 2178264234, 1503431475], x = 1656773520, y = 3461928145 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.

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 232 1: set b 5 2: set c 371 3: set d 413 4: sub b a 5: sub a 70 6: sub b a 7: dec d 8: jnz d -4 9: add a b 10: dec c 11: jnz c -8 12: halt Respond with just the final value of register a.compute-paths-1— unanswered—

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.
