Merge_the_Tools!.py

# Consider the following:

# A string, , of length  where .
# An integer, , where  is a factor of .
# We can split  into  substrings where each subtring, , consists of a contiguous block of  characters in . Then, use each  to create string  such that:

# The characters in  are a subsequence of the characters in .
# Any repeat occurrence of a character is removed from the string such that each character in  occurs exactly once. In other words, if the character at some index  in  occurs at a previous index  in , then do not include the character in string .
# Given  and , print  lines where each line  denotes string .

# Example


# There are three substrings of length  to consider: 'AAA', 'BCA' and 'DDE'. The first substring is all 'A' characters, so . The second substring has all distinct characters, so . The third substring has  different characters, so . Note that a subsequence maintains the original order of characters encountered. The order of characters in each subsequence shown is important.

# Function Description

# Complete the merge_the_tools function in the editor below.

# merge_the_tools has the following parameters:

# string s: the string to analyze
# int k: the size of substrings to analyze
# Prints

# Print each subsequence on a new line. There will be  of them. No return value is expected.

# Input Format

# The first line contains a single string, .
# The second line contains an integer, , the length of each substring.

# Constraints

# , where  is the length of 
# It is guaranteed that  is a multiple of .
# Sample Input

# STDIN       Function
# -----       --------
# AABCAAADA   s = 'AABCAAADA'
# 3           k = 3
# Sample Output

# AB
# CA
# AD
# Explanation

# Split  into  equal parts of length . Convert each  to  by removing any subsequent occurrences of non-distinct characters in :

# Print each  on a new line.
