I think there is problem with complier

#1

#include<bits/stdc++.h>
using namespace std;

int ans(int n,vector&arr,int k){
if(n==0){
return 0;
}

int l = 0;
int count_0 = 0;
int maximum = 0;

for(int i=0;i<n;i++){
if(arr[i]==1){
continue;
}

 if(arr[i]==0){
	 count_0++;
 }

 while(count_0>k){
	 if(arr[l]==0){
		 count_0--;
		 l++;
	 }
 }

 maximum = max(maximum,i-l+1);

}

return maximum;

}

int main() {
int n;
cin>>n;
int k;
cin>>k;
vectorarr;
for(int i=0;i<n;i++){
int x;
cin>>x;
arr.push_back(x);

}

cout << ans(n,arr,k) << endl;

}

a) write l++ outside ur if statement otherwise it will run in inifinite loop
b) check output format u need to print modified array as well
