In place of calculating the factorial several times we can run a loop k times to calculate the combination (#10051)
* In place of calculating the factorial several times we can run a loop k times to calculate the combination 

for example:
5 C 3 = 5! / (3! * (5-3)! )
= (5*4*3*2*1)/[(3*2*1)*(2*1)]
=(5*4*3)/(3*2*1)
so running a loop k times will reduce the time complexity to O(k)

* Let's use self-documenting variable names

I am not sure if `nbor` was supposed to be `neighbour`.  ;-)
