LeetCode首战:解Two Sum 📚 今日挑战:LeetCode的Two Sum问题。给定一个整数数组和一个目标值,找出数组中和为目标值的两个整数,并返回它们的索引。💡 解题思路:首先,我们遍历数组,对于每个元素,计算目标值与当前元素的差值,并在剩余的数组中查找该差值是否出现。如果找到,则返回这两个元素的索引。
Leetcode c++语言 方法/步骤 1 问题描述：给定一个整数数组，返回两个数字的索引，使它们相加的值等于一个特定的目标值。假设对于每个输入只有一种解决方案，并且您不可以两次同时使用相同的元素。2 问题的示例：给定nums = [2,7,11,15]， target = 9，因为nums[0] + nums[1] = 2 + 7 = 9，返回[0,...
