Given an array of positive and negative numbers. If the sum exists, then return true, Also, insert every prefix sum into a map, so that later on it can be found whether the current sum is seen before or not, At the end return false, as no such subarray is found. At any moment, when the count of 0s and 1s are the same, maximize the length of the subarray.Let us understand this approach with an example: Time Complexity: O(N), where N is the size of the array A[], In 4 simple steps you can find your personalised career roadmap in Software development for FREE, Smallest Positive Missing Number (Solution), Best Courses for Data Structures & Algorithms- Free & Paid, Best Machine Learning Courses Free & Paid, Best Full Stack Developer Courses Free & Paid, Best Web Development Courses Free & Paid, Traverse through the array and if the current element.
