Write a Python program which reads an integer n and find the number of combinations of a,b,c and d (0 ≤ a,b,c,d ≤ 9) where (a + b + c + d) will be equal to n.
n (1 ≤ n ≤ 50)
import itertools print("Input the number(n):") n=int(input()) result=0 for (i,j,k) in itertools.product(range(10),range(10),range(10)): result+=(0<=n-(i+j+k)<=9) print("Number of combinations:",result)
Input the number(n): 15 Number of combinations: 592
