#+STARTUP: indent content #+TODO: TODO UNFINISHED WORKING | DONE * DONE 146 - Supposed to be solved with cpp stl, perhaps a c implementation of next_permutation will be more exciting? * DONE 429 - Word transformation: looks like a graph problem - Appears under 'easy BFS' - Needs to be revisited * UNFINISHED 12532 - On uhunt this problem is put under 'tree-related structures', but not sure how a tree might be useful in this case - A segment tree perhaps? - Attempting a (naive) linear array first to see if it works (half expecting it to fail on time limit) - Failed on TLE * TODO 924 - Involves finding the depth with maximum number of nodes from a given node - BFS with keeping track of queue sizes for each depth
