5.【题解】Same GCDs
题解 思路 计算有多少个 \(x(0\leq x<m)\) 使得 \(\gcd(a,m)=\gcd(a+x,m)\) 事实上就是求有多少个 \(x(1\leq x\leq m)\) 使得 \(\gcd(x,m)=\gcd(a,m)\) 所以可以将 \(m\) 除以 \(\gcd(a,m)\) ，于是 ......

（待完善）Same data type with different length
首先，问题的前提是：不同数据类型的实际大小是依赖于编译器的具体实现的，那么假设在一个long为8B的平台，使用long作为例如memcpy的参数进行数据移动，并且指定的要移动的字节数超过了4B所能表示的最大值，那么如果将此代码移动到一个long为4B的平台，代码就会出现问题，因为此时的long已无法 ......
