Two Sum II - Input array is sorted

Two Sum II - Input array is sorted: Problem Description: Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Note: Your returned answers (both index1 and index2) are not zero-based. You may assume that each input would have exactly one solution and you may not use the same element twice.   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. Example 2: Input: numbers = [2,3,4], target = 6 Output: [1,3] Example 3: Input: numbers = [-1,0], target = -1 Output: [1,2]   Constraints: 2 <= nums.length <= 3 * 104 -1000 <= nums[i] <= 1000 nums is sorted in increasing order. -1000 <= target <= 1000 Program: class Solution {     public int[] twoSum(int[] num...
