N-r nPr n. C Program to Implement SJF CPU Scheduling Algorithm. This C Program makes use of the Factorial Function in C Programming to find the Value of nCr.
C Program to Implement SJF CPU Scheduling Algorithm.
NCr is also commonly written as Cnr. Find nCr and nPr in C. Ncr find_ncr n r. To find combination we use the concept of finding factorial of a number and use the standard formula for nCrnrn-r.
