We don't need to iterate the last index in the array as (i+1)th element for that index will be out of bound. The the elements of the matrix are arcs(for example 9-31 is the arc between nodes 9 and 31),so i want to make enough exchanges to reduce the cost. A protip by fabsays about ruby and arrays. Example: Input: Array elements are: 10, 20, 30, 40, 50 Output: Array elements after swapping (reversing): 50, 40, 30, 20, 10. Then your program will write out the array. So in each pass, you need to swap the elements at most one time. Everything I can find either defines it in terms of a mathematical formula or suggests some of the uses of it. Basically I have a 2d array with 2 rows, and I want to take a few of the elements from one and put them in the other, getting a new array that has elements of both.
