Two Sum II - Input Array Is Sorted– LeetCode Problem

Problem:

Given a 1-indexed array of integers  that is already sorted in non-decreasing order, find two numbers such that they add up to a specific  number. Let these two numbers be  and  where .

Return the indices of the two numbers,  and , added by one as an integer array  of length 2.

The tests are generated such that there is exactly one solution. You may not use the same element twice.

Your solution must use only constant extra space.

Example 1:

Input: numbers = [2,7,11,15], target = 9 Output: [1,2] Explanation: The sum of 2 and 7 is 9. Therefore, index₁ = 1, index₂ = 2. We return [1, 2].

Example 2:

Input: numbers = [2,3,4], target = 6 Output: [1,3] Explanation: The sum of 2 and 4 is 6. Therefore index₁ = 1, index₂ = 3. We return [1, 3].

Example 3:

Input: numbers = [-1,0], target = -1 Output: [1,2] Explanation: The sum of -1 and 0 is Therefore index₁ = 1, index₂ = 2. We return [1, 2].

Constraints:

•  is sorted in non-decreasing order.
• The tests are generated such that there is exactly one solution.
