This is the solution to this UVa problem Code #include <iostream> #include <iostream> #include<bits/stdc++.h> #define pb push_back #define T 50005 using namespace std; int p[T]; int r[T]; void ini(int n){ for(int i=0;i<n;i++){ p[i]=i; r[i]=1; } } int root(int a){ while(p[a]!=a){ p[a]=p[p[a]]; a=p[a]; } return a; } void joint(int a,int b){ if (a==b) return; a=root(a); b=root(b); if (a == b) return; if(r[a]>r[b]){ r[a]+=r[b]; p[b]=a; return; } r[b]+=r[a]; p[a]=b; } bool query(int a, int b){ return p[a]==p[b]; } int main() { std::ios::sync_with_stdio(false); int breaker; cin>>breaker; int test=0; while(1){ test++; if(test>breaker) break; int n,m; cin >> n>>m; if(n==0 && m==0) break; ini(n); while(m--){ int i,j; cin>>i>>j; joint(i-1,j-1); } int counter=0; int maxi=0; for(int i =0;i<n;i++){ maxi=max(maxi,r[i]); } cout...
