Read MorePermutation and Combination in Java
Permutation and Combination are a part of Combinatorics. Permutation is the different arrangements that a set of elements can make if the elements are taken one at a time, some at a time or all at a time. Combination is is the different ways of selecting elements if the elements are taken one at a time, some at a time or all at a time.An example of this is given as follows −Permutation = factorial(n) / factorial(n-r); Combination = factorial(n) / (factorial(r) * factorial(n-r)); n = 5 r = 3 Permutation = 60 Combination = 10A program that demonstrates this ...
