Monday, 21 November 2016. arr=[1,2,3,4,6] The sum of first three elements, 1+2+3=6, The value of the last element is 6. Andy wants to play a game with his little brother, Bob. Stacks are represented as an array, and the first index of the array represent the top element of the stack. Example. Objective Today, we're learning about the Array data structure. The hardest part about this problem is to understand what is it actually saying. You are given an array \(A\) of size \(N\). Determine the number of pairs of array elements that have a difference equal to a target value. Solution : … He wants to reduce the array until all remaining elements are equal. Watson gives Sherlock an array of integers.
