Binary representation

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

• Time : O(1)
• Space : O(1)

class Solution
{
public:
    string getBinaryRep(int N)
    {
        string res = "";
        for(long long i = 29; i >= 0; i--) {
            res.push_back((bool)(N & (1<<i)) | 0b110000);
        }
        return res;
    }
};
