Do anybody know what is mistake:
#include<iostream>
#include<vector>
using namespace std;
int main()
{
    int n,m;
    cin>>n>>m;
    vector<int> a,b,count;
    a.resize(m);
    b.resize(n);
    count.resize(n);
    for(int i=0;i<m;i++){
    cin>>a[i];}
    for(int i=0;i<n;i++){
    b[i]=i+1;
    count[i]=0;}
    for(int i=0;i<n;i++){
    for(int j=0;j<m;j++){
    if(b[i]==a[j]){
    count[i]++;}}}
    vector<float> c;
    c.resize(n);
    for(int i=0;i<n;i++){
    if(count[i]>0){
    c[i]=m/count[i];
    c[i]=100/c[i];
    cout.precision(2);
    cout<<fixed<<c[i]<<"%"<<endl;}
    else{
    c[i]=count[i];
    cout.precision(2);
    cout<<fixed<<c[i]<<"%"<<endl;}}
    return 0;
}

I got WA#3

I HAVE WA N12.did you thinked about 0.00% percent
