Top Problems on Prefix Sum Technique for Interviews

The Prefix Sum Technique is a powerful and widely used approach in coding interviews, especially for optimizing queries related to subarray sums and cumulative computations.

Easy Problems

• Equilibrium Index
• Split an array into two equal Sum subarrays
• Mean of range in array
• Original Array from Prefix Sums

Medium and Hard Problems

• Product of Array Except Self
• Longest Subarray With Sum K
• Minimum Removals for Target Sum
• Subarray with 0 sum
• Longest Span in two Binary Arrays
• Largest Submatrix With Sum 0
• Maximum occurring integer in given ranges
• Compute before Matrix
• Maximum occured integer
• Longest Span with same Sum in two Binary arrays
• Maximum sum Rectangle
• Subarray Sum Divisible By K
• Count Subarrays having Sum K
• Smallest sum contiguous subarray
