What’s the error?
I have cleared all the given test cases and I also ran some of my own, it all worked fine but I’m getting Wrong answer after submitting.

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

int main(){
	int test;
	cin >> test;
	while(test--){
		int n;
		cin >> n;
		int logi = (int) log2(n);
		int power = (int) pow(2, logi);
		int step =  n - power + 1;
		cout << step << endl;
	}
}

#include
using namespace std;
int steps(int n){
int bit=0;
while(n!=0){
if(n&1){
bit++;
}
n=n>>1;
}
return bit;
}
int main(){
int n;
cin>>n;
while(n–){
int num;
cin>>num;
cout<<steps(num)<<endl;
}
}
