Introduction To Python
Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

itertools.combinations() in Python – HackerRank Solution
This tool returns the r length subsequences of elements from the input iterable.
Combinations are emitted in lexicographic sorted order. So, if the input iterable is sorted, the combination tuples will be produced in sorted order.
Sample Code :
>>> from itertools import combinations >>> >>> print list(combinations('12345',2)) [('1', '2'), ('1', '3'), ('1', '4'), ('1', '5'), ('2', '3'), ('2', '4'), ('2', '5'), ('3', '4'), ('3', '5'), ('4', '5')] >>> >>> A = [1,1,3,3,3] >>> print list(combinations(A,4)) [(1, 1, 3, 3), (1, 1, 3, 3), (1, 1, 3, 3), (1, 3, 3, 3), (1, 3, 3, 3)]
You are given a string S.
Your task is to print all possible combinations, up to size k, of the string in lexicographic sorted order.
Input Format :
A single line containing the string S and integer value k separated by a space.
- 0 < k <= len(S)
The string contains only UPPERCASE characters.
Output Format :
Print the different combinations of string S on separate lines.
Sample Input :
Sample Output :
A C H K AC AH AK CH CK HK
