1358 Number Of Substrings Containing All Three Characters

Understanding the Problem

The 1358 problem is a coding challenge that requires you to find the number of substrings in a given string that contain all three characters. This problem is a great example of how to apply string manipulation and counting techniques to solve a real-world problem. In this article, we will break down the problem and provide a step-by-step solution to help you understand how to solve it.

To start solving the problem, you need to understand the constraints and the requirements. The problem statement provides a string and asks you to find the number of substrings that contain all three characters. The string can contain any combination of characters, and the substrings can be of any length. The goal is to count the number of substrings that meet the condition.

Solving the Challenge

The key to solving this problem is to use a sliding window approach. This involves iterating over the string and maintaining a window of characters that meet the condition. You can use a dictionary or a hash map to keep track of the characters in the window and their frequencies. As you iterate over the string, you can update the window and count the number of substrings that meet the condition.

To solve the challenge, you can use a programming language like Python or Java. The solution involves iterating over the string, maintaining a window of characters, and counting the number of substrings that meet the condition. You can use a loop to iterate over the string and a conditional statement to check if the substring meets the condition. With a little practice and patience, you can solve the 1358 problem and improve your coding skills.
