The Fibonacci series is a sequence of integers in which the first two integers are 1 and from third integer onwards each integer is the sum of the previous two integers of the sequence i.e. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ………………………….. The program which implements the above logic is […]

The GCD or HCF (Highest Common Factor) of two integers is the greatest integer that divides both the integers with remainder equals to zero. This can be illustrated by Euclid’s remainder Algorithm which states that GCD of two numbers say x and y i.e. GCD(x, y) = x if y is 0 = GCD(y, x%y) […]
