Question

change this mathemathical equation into algorithm.where n are r inputs from the user.C(n,r)=nCr

Answer 1

Algorithm? As in writing programming language?

Firstly I would declare function name factorial where it will loop, multiplying input by integers smaller than itself until it reaches 1, then return result.

This function would be helpful here since \(_nC_r = \dfrac{n!}{r!(n-r)!}\)

As you can see, you would need to call factorial function three times.

Answer 2

Let me know if this isn't what you are looking for.

Answer 3

but how can i change the factorial in to algorithm???
