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) run
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 ...
Given a binary string s, you can split s into 3 non-empty strings s1, s2, and s3 where s1 + s2 + s3 = s. Return the number of ways s can be split such that the number of ones is the same in s1, s2, and s3. Since the answer may be too large, return it modulo 109 + 7...
