Compress the String! solved

This Python program takes a string as input and compresses it by grouping consecutive identical characters. The compressed string is then printed out, with each group represented by a tuple containing the length of the group and the character itself.

Here is the Compress the String! solved HackerRank solution using CodeRankGPT:

The solution uses the 'groupby' function from Python's 'itertools' module to group consecutive identical characters in the input string. It then iterates over these groups, printing out a tuple for each one. The tuple contains the length of the group (i.e., the number of times the character is repeated consecutively) and the character itself.


import itertools

s = input().strip()
s_unique_element = list(set(s))
group = []
key = []
for k, g in itertools.groupby(s):
    group.append(list(g))
    key.append(k)
for i in range(len(group)):
    group_length = len(group[i])
    k = int(key[i])
    print((group_length, k), end=" ")

If you have a HackerRank coding test coming up, you can use CodeRankGPT to your advantage. It will assist you during your interview and help ensure you get the job.
