I tried putting print statements all over the place, but the only thing I came to is that 1 too many elements get added to the list - hence, the last if statement (to drop the last added element), but it made no difference whatsoever, so it's probably wrong. Are you sure you want to create this branch? How do I concatenate two lists in Python? How do I align things in the following tabular environment? For further actions, you may consider blocking this person and/or reporting abuse. Since there are exactly N numbers spread throughout the buckets, and since it only requires a single iteration of each number in a bucket to observe the local high and lo values (currhi, currlo), then it will take a total of O(N) time to perform this process for the entire buckets array.

Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. To achieve the right bucket size (bsize) for this to work, we'll need to iterate through nums once to find the total range (hi - lo), then use that to figure out the absolute smallest possible maximum gap value ((hi - lo) / (nums.length - 1)). You signed in with another tab or window. Programming Languages. Longest Substring Without Repeating Characters 4. We'll just need to make sure that we remember the previous occupied bucket's high value (prevhi) for the next comparison, as well as keeping track of the best result found so far (ans).
