Amazon Online Assessment (OA) - Find Substrings Given a string S of lowercase letters. You need to find as many substrings from the S that meets the following conditions. no overlap among substrings one letter can only exist in one substring. For every letter C in a substring, all occurrences of the letter C also need to be in that substring.find the number of ‘01’ strings starting at each index of the string (based on 1.) find the number of ‘101’ strings starting at each index of the string (based on 2.) This is similar to the Paint Fence problem. Leetcoding is a great way to prevent a false positive. But it can also give a false negative.

Naive approach is really easy. Calculate all distances then sort array and return top n. Another approach is classic top k elements. Calculate all distances, put n elements in max heap. For each remaining element, pop/push heap if curr distance is less then top element in heap. 22. Amazon Online Assessment (OA) is the first online test / assessment conducted on online coding platforms like HackerRank or Codility that an applicant to Amazon needs to take to get into Software Developer Engineer (SDE) role at Amazon. The result in Amazon OA determines if the candidate will move forward to phone or on-site Interviews where you interact with an Amazon Engineer. Amazon OA is divided into 3 parts: Return type. The CHARINDEX function returns an integer corresponding to the position of the substring (one-based, not zero-based). The position is based on the number of characters, not bytes, so that multi-byte characters are counted as single characters. For substring abbb, you have most frequent letter b -> 3 and least frequent letter a -> 1. So the deviation is = most frequent - least frequent = 3 - 1 = 2. You need to look at all the substrings and find the max deviation. Questions for OA2.
