Given an array that has n integers, count the number of ways to split all elements of this array into 3 contiguous parts so that the sum of each part is the same. Each part must not be empty. Algorithm: O(N) runtime 1. If total sum % 3 != 0, return 0. 2. Keep a count of...
Given a binary string s (a string consisting only of '0’s and '1’s), we can split s into 3 non-empty strings s1, s2, s3 (s1+ s2+ s3 = s). Return the number of ways s can be split such that the number of characters ‘1’ is the same in s1, s2, and s3. Since the ...

Explanation: There are four ways to split s in 3 parts where each part contain the same number of letters ‘1’. “1|010|1” “1|01|01” “10|10|1” “10|1|01” Example 2: Input: s = “1001” Output: 0 Example 3:
Return the number of good splits you can make in s. Example 1: Input: s = "aacaba" Output: 2 Explanation: There are 5 ways to split "aacaba" and 2 of them are good. ("a", "acaba") Left string and right string contains 1 and 3 different letters respectively. ...
