题目167(Two Sum II - Input array is sorted): 问题描述:给定一个按升序排列的整数数组 numbers 和一个目标值 target,请你找出两个数使得它们的和正好是 target。返回这两个数的下标,下标从1开始。 条件:数组已排序。 Two Sum(未排序数组) 由于数组未排序,双指针方法无法直接应用。常见解法是使用哈希表(字典...
The tests are generated such that there isexactly one solution. Youmay notuse 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, ...
函数twoSum应该返回两个数字的索引,使它们相加到目标,其中index1必须小于index2。 请注意,您返回的答案(index1和index2)都不是基于零的。 您可以假设每个输入都将具有一个解决方案,您可能不会使用相同的元素两次。 Input: numbers={2, 7, 11, 15}, target=9 ...
167.Two Sum II - Input array is sorted(双指针法) 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...

reduce() 方法对数组中的每个元素按序执行一个提供的 reducer 函数,每一次运行 reducer 会将先前元素的计算结果作为参数传入,最后将其结果汇总为单个返回值。
There are two arrays with individual values. Write a JavaScript program to compute the sum of each individual index value in the given array.Sample array: array1 = [1,0,2,3,4]; array2 = [3,5,6,7,8,13]; Expected Output: [4, 5, 8, 10, 12, 13]...
