Program to find expected sum of subarrays of a given array by performing some operations Suppose we have an array A whose size is n and two values p and q. We can perform these operations on A. Randomly select two indexes (l, r) where l < r, then exchange A[l] and A[r] ...
In computer science, the maximum sum subarray problem is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers. Formally, the task is to find indices and with, such that the sum is as large as possible. ...
