WebDec 13, 2024 · Since we sorted all the suffixes we can perform a binary search for s in p . Comparing the current suffix and the substring s within the binary search can be done in O ( s ) time, therefore the complexity for finding the substring is O ( s log t ) .

Then each iteration of the binary search cuts the search space in half, so the algorithm tests \mathcal {O} (\log N) O(logN) values. This is efficient and much better than testing each possible value in the search space. how much lithium is in a tesla battery packWebCodeforces-Solutions/474B.
