#include<bits/stdc++.h>

using namespace std;

int main(){

    int flag=0;
    if(n>m) swap(n,m),flag=0;
    vector<pair<int,int>> res;
    
    if(n==m){
        for(int i=1;i<=n;i++) res.push_back({i,1});
        for(int i=2;i<n;i++) res.push_back({i,n});
    }else{
        for(int i=1;i<=n;i++) res.push_back({i,1}),res.push_back({i,m});
        if(n%2){
