    swap(x,y)用来交换两个数的值

    //我是奶龙
    #include <bits/stdc++.h>
    using namespace std;
    int n, q, a[50005];
    
    int main() {
    	cin >> n >> q;
    	for (int i = 1; i <= n; i++)
    		cin >> a[i];
    	while (q--) {
    		int x, y;
    		cin >> x >> y;
    		swap(a[x], a[y]);
    	}
    	for (int i = 1; i <= n; i++)
    		cout << a[i] << " ";
    	return 0;
    }
