A class named demo contains a static function named ‘odd_occurs’. The outer loop will pick a number, and the inner loop will count the frequency of the occurrence of that number. You need to solve it with o(n) time complexity and o(1) space complexity.

Then the problem will become “find ‘one’ number with odd occurrence in an unsorted array”, which becomes a simple problem and will be solved using xor. In order to check the number, we have divided the number by 2 if it leaves a remainder, the number is odd and the print statement prints that number.
