Understanding the Two Sum I I - Input Array Is Sorted Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order, find two numbers such that they add up to a specific target number. Let these two numbers be numbers[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers.length. Return the indices of the two numbers, index1 and index2, added by one as an integer array [index1, index2] 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.

How Interview Coder Helps
Get real-time assistance for Two Sum II - Input Array Is Sorted problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
numbers = [2,7,11,15], target = 9[1,2]The sum of 2 and 7 is 9. Therefore, index1 = 1, index2 = 2. We return [1, 2].
numbers = [2,3,4], target = 6[1,3]The sum of 2 and 4 is 6. Therefore index1 = 1, index2 = 3. We return [1, 3].
numbers = [-1,0], target = -1[1,2]The sum of -1 and 0 is -1. Therefore index1 = 1, index2 = 2. We return [1, 2].
Constraints
2 <= numbers.length <= 3 * 1041000 <= numbers[i] <= 1000numbers is sorted in non-decreasing order.1000 <= target <= 1000The tests are generated such that there is exactly one solution.How Interview Coder Helps with Leetcode Problems
