Can you solve this real interview question? 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
Given an integer array nums and two integers firstLen and secondLen, return the maximum sum of elements in two non-overlapping subarrays with lengths firstLen and secondLen. The array with length firstLen could occur before or after the array with length secondLen, but they have to be non...
Replace the arraynumswithnewNums. Repeat the entire process starting from step 1. Return the triangular sum ofnums. Example 1: Input: nums = [1,2,3,4,5]Output: 8Explanation:The above diagram depicts the process from which we obtain the triangular sum of the array. ...
