My code is correct but time not exceeded ,so how to solve the code
#include
using namespace std;
int main() {
int N;
int no;
cin >> N;

while(N>0){
	 

	cin >> no ;
	int p=1;
	int result=0;

	while( no>0){

	  
	  int rem = no%10;
	   
	   result =  result + rem *p;   

	   p = p*2;
	   no =no/10;                      

}
     cout << result ;
}

     N =N-1;
             
        

return 0;

}

Hello @faizan_1402,

  1. Read the constraints carefully.
    Digits in binary representation is <=16
    Mistake:
    int cannot hold these many digits.
    Solution:
    change the datatype to long long int of no.

  2. The position of decrementing N is wrong.
    Solution:
    Decrement it inside the first while loop.

Hope, this would help.
Give a like if you are satisfied.

Not run code Again showing error
#include
using namespace std;

int main() {
int N;
long long int no;
cin >> N;

while(N–){

cin >> no ;
int p=1;
int result=0;

while( no>0){

  
  int rem = no%10;
   
   result =  result + rem *p;   

   p = p*2;
   no =no/10;

}
cout << result ;
}

 N =N-1;

return 0;
}
