Problem-19 Find the two repeating elements in a given array: Given an array with size, all elements of the array are in range 1 to n and also all elements occur only once except two numbers which occur twice. Find those two repeating numbers. For example: if the array is 4,2,4,5,2,3,1 with size = 7 and n = 5. This input has n + 2 = 7 elements with all elements occurring once except 2 and 4 which occur twice. So the output should be 4 2.

Problem-19
Find the two repeating elements in a given array: Given an array with size,
all elements of the array are in range 1 to n and also all elements occur only once except
two numbers which occur twice. Find those two repeating numbers. For example: if the
array is 4,2,4,5,2,3,1 with size = 7 and n = 5. This input has n + 2 = 7 elements with all
elements occurring once except 2 and 4 which occur twice. So the output should be 4 2.
