Given a sorted array of integers `nums` and a target integer `target`, return `true` if there exist two numbers in the array such that they add up to `target`, otherwise return `false`.
nums = array of integers (sorted), target = target sum to find
true if a valid pair exists, false otherwise
Example 1:
Input:
nums = [1,2,3,4,6] target = 6
Output:
[2,4]
Explanation:
1 + 5 = 6 exists.
Example 2:
Input:
nums = [2,5,9,11] target = 7
Output:
[1,2]
Explanation:
No two numbers sum to 7.
Example 3:
Input:
nums = [-3,-1,0,1,2] target = -2
Output:
[1,4]
Explanation:
-3 + 1 = -2 exists.
