In this **itertools.combinations_with_replacement()** problem we need to develop a python program that can read a string and then we need to use the itertool module and print all possible combinations of string in the lexicographically sorted order on the output screen.

# Problem solution in Python 2 programming.

from itertools import combinations_with_replacement S,k = raw_input().split() k = int(k) print '\n'.join(sorted(''.join(sorted(c)) for c in combinations_with_replacement(S,k)))

## Problem solution in Python 3 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT from itertools import combinations_with_replacement s, n = input().split() print(*[''.join(i) for i in combinations_with_replacement(sorted(s), int(n))], sep="\n")

### Problem solution in pypy programming.

from itertools import combinations_with_replacement source, combos = raw_input().split() sstr = sorted(source) for combo in combinations_with_replacement(sstr,int(combos)): print ''.join(combo)

### Problem solution in pypy3 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT from itertools import combinations_with_replacement s,k = input().split() print('\n'.join(map(''.join,combinations_with_replacement(sorted(s),int(k)))))
