Given a binary array arr[] and an integer target, return the number of non-empty subarrays with a sum equal to the target. Note: A subarray is the contiguous part of the array. Examples: Input: arr[] = [1, 0, 1, 0, 1], target = 2 Output: 4 Explanation: There are four subar...

After the fix your algorithm will return 8, instead of the correct 5 (it remove the first 5 numbers) As far as I know there is no greedy solution to the problem. This problem is equivalent to finding a subarray of maximum size with a sum equal to K (the numbers you leave). This ...

Explanation: [0, 1] (or [1, 0]) is a longest contiguous subarray with equal number of 0 and 1. Recommend that you read this first:Algorithms to Find Maximum Size Subarray (Contiguous) Sum That Equals k. Then, the problem can be transformed to: Given an array of numbers that only co...
