Problem Statement for "CopyingHomework"

Problem Statement

  • "Dude, can I copy your homework?"
  • "Sure, but change it a little, so it doesn't look like we cheated."

You are given the int[] friendsHomework containing the five values your friend measured for their Physics homework. Construct and return a int[] yourHomework with the following properties:

  • yourHomework must have exactly 5 elements.
  • For each i, yourHomework[i] must differ from friendsHomework[i] (so it doesn't look like you cheated).
  • For each i, the difference between yourHomework[i] and friendsHomework[i] must be at most 10 (so that the values are similar).
  • The sum of yourHomework must be the same as the sum of friendsHomework (so that you both get the same final result).

Examples

  1. {10, 20, 30, 40, 50}
