Problem: Write a c program to solve the number of stopping station problem in c language. Here is the same program in python programming language.
1 2 3 4 | Algorithm Input : total numbers of stations n and number of stations train can stop r. Step 1 : For values of n and r calculate the value of p(n,r) = n! / (n-r)! Step 2 : print the value of p(n,r) using std print method. |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | #include<stdio.h> int main(){ int n = 16, s = 6; printf("Total number of stations = %d\nNumber of stopping station = %d\n", s, n); int p = s; int num = 1, dem = 1; while (p!=1) { dem*=p; p--; } int t = n-s+1; while (t!=(n-2*s+1)) { num *= t; t--; } if ((n-s+1) >= s) printf("Possible ways = %d", num / dem); else printf("no possible ways"); } |
Program Output
Total number of stations = 16
Number of stopping station = 6
Possible ways = 462
