Matrix Chain Multiplication
1. You are given an array(arr) of positive integers of length N which represents the dimensions of N-1 matrices such that the ith matrix is of dimension arr[i-1] x arr[i]. 2. You have to find the minimum number of multiplications needed to multiply the given chain of matrices.
2 <= N <= 1000 1 <= arr[i] <= 500
A number N arr1 arr2.. N integers
