This problem can be solved with a brute force search approach, or with a more advanced and efficient sliding window technique. Let us discuss certain ways in which this task can be performed in Python. In another words does abcabc encode to abc2? Jul 12, 2025 · Approach: The idea is to iterate over all the substrings. Below is the implementation of the above approach: String Compression - Given an array of characters chars, compress it using the following algorithm: Begin with an empty string s. For each group of consecutive repeating characters in chars: * If the group's length is 1, append the character to s. count (char)) for char in set (text)] Mar 11, 2024 · The str. # Code text = "aaabbbbcc" consecutive_counts = [ (char, text. Sep 1, 2021 · 2 This is the question I tried Leetcode: String Compression Given an array of characters chars, compress it using the following algorithm: Begin with an empty string s. How to replace all but 2 consecutive repeat characters B. For example, if my input is: abceeedtyooo The output should be: 2 Feb 7, 2019 · 5 I need to make a function that replaces repeated, consecutive characters with a single character, for example: This lesson focuses on parsing a given string to identify and group consecutive repeating characters. * Otherwise, append the character followed by the group's length. I need to find the longest sequence in a string with the caveat that the sequence must be repeated three or more times. For each group of consecutive repeating characters in chars: # # # If the group's length is 1, append the character to s. We need to store this group in the modified character Consecutive Characters - The power of the string is the maximum length of a non-empty substring that contains only one unique character. In the end return this count as count of all unique substrings with non-repeating characters. Given a string s, return the power of s. Jul 19, 2023 · Step 4: If the current character is different from the previous one, it means the current group of consecutive repeating characters has ended. com/grandakt/joy#Write a program to count the number of times a character occurs in the giv Mar 18, 2024 · Here’s how it works: First, we need to scan through the input data while looking for consecutive repeating characters Then, when we find a consecutive repeating character, we’ll replace it with the character followed by the number of times it appears Finally, the compressed output is the modified input data with repeating characters Are the repeating characters an arbitrary length. takeuforward is the best place to learn data structures, algorithms, most asked coding interview questions, real interview experiences free of cost. Aug 22, 2011 · Since I nested the parentheses, group number 2 refers to the character matched by \w. count() method is the most straightforward way to find the number of occurrences of a character in a string. Sep 11, 2020 · Need to find the count of each consecutive character in a row. A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters Longest Consecutive Sequence - Given an unsorted array of integers nums, return the length of the longest consecutive elements sequence. Return the length of the longest substring containing the same letter you can get after performing the above operations Can you solve this real interview question? Longest Substring Without Repeating Characters - Given a string s, find the length of the longest substring without duplicate characters. Description Given an array of characters chars, compress it using the following algorithm: Begin with an empty string s. 3. You can perform this operation at most k times. Jul 23, 2025 · The count of consecutive substrings is stored in a list, and this list is returned as the output.

I also need to maintain the orig Apr 7, 2025 · After the string traversal, traverse the visited array and check if value in the array is not equal to -1 or -2 (means, this character is not repeating). also, if you repeated it twice, it would try and find triples since the first group is counted as the first occurence. You can choose any character of the string and change it to any other uppercase English character.
