Write a program to print Binary representation of a given number N.

Example 1:

Input:
N = 2
Output:
000000000000000000000000000010
Explanation:
The binary representation of 2 is '10'
but we need to print in 30 bits so append
remaining 0's in the left.

ANSWER:

string getBinaryRep(int N)
    {
        vector<int> vec;
        while(N>0)
        {
            int rem=N%2;
    
            vec.push_back(rem);
            
            N=N/2;
        }
        
       
        int l=30-vec.size();
        for(int i=0;i<l;i++)
        {
            vec.push_back(0);
        }
        
        string s="";
        for(int i=vec.size()-1;i>=0;i--)
        {
            if(vec[i]==1)
            {
                s=s+"1";
            }
            else
            {
                s=s+"0";
            }
        }
        return s;
    }
