1.两数之和(简单) https://leetcode-cn.com/problems/two-sum/solution/1liang-shu-zhi-he-by-notmaster/ 备注：久闻 leetcode 大名，但是今天才正式使用，所以还花了一点时间研究软件本身，先立个目标，训练营期间计划每天一题。因为本题难度简单，所以实际上还做了第二题【两数相加(中等)】，第二题难度增加不少，本地调试能过，提交老是过不了，准备研学习下其他人的多种解法后再写题解。

【1】两数之和 解题思路： 利用两次循环，拿出数组的一项，和数组的其余项求和，再和目标值对比 个人感受是比较通俗的解法，肯定也不是最优答案 需要花时间了解一下时间复杂度，空间复杂度，找到性能最好的解法 https://leetcode-cn.com/problems/two-sum/solution/1-liang-shu-zhi-he-walle-algorithm-journey-by-xiao/ 刚开始接触算法领域，望各位大佬多多指教
