void swap(int a,int b){
int s=a;
a=b;
b=s;
}
int main(){
int x=1,y=2;
swap(x,y);
}
上面的函数并不能实现交换,因为传参相当于赋值
把x,y传给函数swap(),实际发生了:
int a=x,int b=y只是把x,y的值赋给a...
10-排序6 Sort with Swap(0, i) (25point(s))
Given any permutation of the numbers {0, 1, 2,..., N−1}, it is easy to sort them in increasing order. But what if Swap(0, *) is the ONLY operation that is...
