Write a program to input an even number N from the user. Next using a loop simultaneously generate all numbers from (N//2-1) to 1 and (N//2+1) to (N-1). After each pair of values is generated, check if the higher value is twice the lower value. If so, then print those pair of values.
For example, if N=24, pair of values generated will be (11,13), (10,14), (9,15), (8,16), (7,17), (6,18), (5,19), (4,20), (3,21), (2,22), (1,23) and for the pair (8,16), condition 2nd number is twice the 1st number is valid. Hence will print (8,16).
