Find the permutations

Problem to find the possibility of the combination based on the given input and k value.

Example-1:

Input    : n = "123" k = 3
Output   : 123 132 213 231 312 321 

Example-2:

Input    : n = "123" k = 2
Output   : 12 13 21 23 31 32 

Solution

from itertools import permutations

n = "123"

k=3

d = list(permutations(n,k))

for i in range(len(d)):

    print("".join(d[i]),end=" ")

Output

123 132 213 231 312 321
