Counting depth increases and sliding windows. Sometimes Excel is the right tool for the job.
Piloting a submarine with regex-parsed commands. Tuples and TypeScript inference doing the heavy lifting.
Counting bits, filtering reports, and resisting the urge to do actual bit twiddling. Sometimes strings are fine.
Playing Bingo with a cephalopod, debugging for-loop mutations, and learning when to let the squid win.
Mapping vent lines on a grid, handling diagonals, and accepting that a million cells is fine.
Exponential growth, the limits of simulation, and why counting states beats tracking individuals.
Aligning crab submarines, brute force optimization, and rediscovering Gauss's childhood trick.
Decoding scrambled seven-segment displays through logical deduction. Like Sudoku, but with wires.
Finding low points in height maps, flood-filling basins, and padding matrices to avoid boundary checks.
Finding mismatched brackets with stacks, completing incomplete lines, and the eternal developer game of balancing parentheses.
Cascading flashes in an octopus grid. Padding matrices, sentinel values, and waiting for synchronization.
Graph traversal through caves with small/big cave rules. Recursion, path counting, and accepting slow solutions.
Folding transparent paper and watching dots overlap. Sometimes the answer is literally spelled out for you.
When your string explodes exponentially, it's time to break the chains.
