Number Of MCQs - 92

You are given an array(ARR) of length 'N', consisting of non-negative integers. Using only these given numbers, rearrange the numbers in such a way that the resultant number thus formed is the largest possible. You cannot change the order of digits of a number.

For Example:

Given array numbers 12, 5, 34, the largest number you can form with them is 53412. There are other possible arrangements like 51234 or 34125, but they are both less than 53412.

Note:

As the final number formed after concatenation can be very large, print it as a string.

Given a number ‘N’, you are supposed to calculate the number of 1s in the binary representation of the given number.

For example:

Given ‘N’ = 4, 
Its binary representation is 0..0100, therefore there is only 1 set bit, hence the answer will be 1.
