#define a function named binary on which various operations will be performed to get the binary ouput of a number.

#an empty string y is defined to store the output.

#if x>0 the remainder will be calculated and it will be converted into a string and will be added to the empty string y and x//2 will be the new value of x.
         while x>0:
