PERMUT(n,nc)

This function gives the number of Permutations for a given number of objects.
A permutation, also called an "arrangement number" or "order," is a rearrangement of the elements of an ordered list.
A selection of objects in which the order of the objects matters.
A Permutation is an ordered Combination.
In $PERMUT(n,nc)$ , $n$ is an integer which is indicating the number of objects and $nc$ is an integer which is indicating the number of objects in each permutation.
For $n$ and $nc$ ,when we are giving in to decimals it will change in to integers.
The formula for the number of permutation is: $_{n}P_{k}={\frac {n!}{(n-k)!}}$
The Permutation is denoted by $_{n}P_{k}$ , $P_{n,k}$ , or $P(n,k)$ .This function will give the result as error when

1. $n$  and  $nc$  are non-numeric.
2.Suppose  $n\leq 0$   or   $nc<0$  or  $n<nc$ .

PERMUT(14,2)=182
PERMUT(50,5)=254251200
PERMUT(10.2,3)=720
PERMUT(4,0)=1
PERMUT(6,1)=6
