Problem: There is a cave.

The cave has N rooms and M passages. The rooms are numbered 1 to N, and the passages are numbered 1 to M. Passage i connects Room A_i and Room B_i bidirectionally. One can travel between any two rooms by traversing passages. Room 1 is a special room with an entrance from the outside.

It is dark in the cave, so we have decided to place a signpost in each room except Room 1. The signpost in each room will point to one of the rooms directly connected to that room with a passage.

Since it is dangerous in the cave, our objective is to satisfy the condition below for each room except Room 1.

* If you start in that room and repeatedly move to the room indicated by the signpost in the room you are in, you will reach Room 1 after traversing the minimum number of passages possible.



Determine whether there is a way to place signposts satisfying our objective, and print one such way if it exists.

Constraints

* All values in input are integers.
* 2 \leq N \leq 10^5
* 1 \leq M \leq 2 \times 10^5
* 1 \leq A_i, B_i \leq N\ (1 \leq i \leq M)
* A_i \neq B_i\ (1 \leq i \leq M)
* One can travel between any two rooms by traversing passages.

Input

Input is given from Standard Input in the following format:


N M
A_1 B_1
:
A_M B_M


Output

If there is no way to place signposts satisfying the objective, print `No`.

Otherwise, print N lines. The first line should contain `Yes`, and the i-th line (2 \leq i \leq N) should contain the integer representing the room indicated by the signpost in Room i.

Solution:
#include <iostream>
#include <vector>
#include <queue>
using namespace std;

#define pb push_back

vector<vector<int> > a;

int main() {
	int n,m; cin >> n >> m;

	a = vector<vector<int> > (n+1);

	for(int i=0;i<m;i++) {
		int u,v; cin >> u >> v;
		a[u].pb(v); a[v].pb(u);
	}

	vector<int> dist(n+1,-1);

	queue<int> q; q.push(1); dist[1] = 0;

	while(!q.empty()) {
		int x = q.front(); q.pop();

		for(int y:a[x]) {
			if(dist[y] == -1) {
				q.push(y);
				dist[y] = x;
			}
		}
	}

	for(int i=1;i<=n;i++) {
		if(dist[i] == -1) {
			cout << "No"; return 0;
