Leetcode Problem-167 Two Sum II — Input Array Is Sorted [Medium] (Java)

Welcome to the 167th coding challenge of leetcode problem series. My aim to provide more than just solutions. In each leetcode problem, expect a comprehensive breakdown of the code, a deep dive into the techniques employed, and a thoughtful exploration of why we opted for a specific approach. Join me as I embark on this journey of problem-solving, where each challenge serves as a stepping stone to honing our coding skills and making informed algorithmic choices. Welcome to a series that not only solves problems but also demystifies the thought processes behind effective coding solutions.

LeetCode Problem-167 Two Sum II — Input Array Is Sorted

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.
