#include<bits/stdc++.h>
using namespace std;
#define FOR(i,s,t) for(int i=(s),_t=(t); i<=_t; ++i)
const int N=1e6+50;
int deg[N];
int main() {
ios::sync_with_stdio(false);
cin.tie(nullptr);
int n,m;
cin >> n >> m;
vector<pair<int,int>> g;
FOR(i,1,m) {
int x,y;
cin >> x >> y;
deg[x]^=1;
deg[y]^=1;
}
int res=0;
if(n%2==0) {
if(m%2==1) res=m;
} else {
FOR(i,1,n) if(deg[i]==(m&1)) ++res;
}
cout << res << '\n';
return 0;
}
这程序好像有点Bug,我给组数据试试?
