这个问题并计算质数了一下相间隔似的.思想上一致. 注意问题: 1 i 可能 大于或等于j -- 这里上传.小心阅读题意,我没有说这个地方不能保证.需要特殊处理 2 计算过程中可能溢出,的整数大于最大值,需要使用long long 关于效率和时间问题: 1 能够使用数组保存中间结果,这样执行快了.内存消耗大了, 2 能够不使用中间数组. 这样执行肯定比較慢了.可是内存消耗小,一样能够AC的. 全部没有个标准吧.看情况而定.假设须要速度就添加数组,假设省内存就不使用数组吧. 这样的题目一般都使用数组…

这是一道很坑爹的题,一定注意输入的两个数的大小,并且不能简单的交换,因为在最后的输出的时候还需要将原来的数按照原来的顺序和大小,这就是为什么还得开辟两个值得原因 Description Problems in Computer Science are often classified as belonging to a certain class of problems (e.g., NP, Unsolvable, Recursive). In this problem you will be…
