Note that some processors use PUSH/PULL, but in the Intel world, we use PUSH/POP. This is just a "mnemonic" anyway, which basically means an English word for a machine operation. All assembly boils down to an opcode or number which is processed by the CPU. That means, you can call ...

完美数 https://leetcode-cn.com/problems/perfect-number/ 难度:简单 解题思路: 设计一个判断单个数是否是自除数的函数,比如取名为IsSelfDIv() IsSelfDIv函数的要点是: 排除数位中含有0的数 排除原数不是末位数字倍数的数 遍历原数列,对每一个数调用一次进行IsSelfDIv函数,将满足要求的加入List中即可 ...
