/* 
 * Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
 * 
 * You may assume no duplicates in the array.
 * 
 * Example 1:
 * 
 * Input: [1,3,5,6], 5
 * Output: 2
 * Example 2:
 * 
 * Input: [1,3,5,6], 2
 * Output: 1
 * Example 3:
 * 
 * Input: [1,3,5,6], 7
 * Output: 4
 * Example 4:
 * 
 * Input: [1,3,5,6], 0
 * Output: 0
