Python: Optimal Partition of Strings | Python Interview Questions | DE Interview Questions | FAANG

Video 177: In this video, we are going to partition the string into one or more substrings. In this problem, we are tasked with partitioning a given string into substrings such that each substring contains unique characters. The goal is to determine the minimum number of substrings required for this partitioning. *** Approach 1: Iterative Approach with Unique Character Tracking *** This approach iterates through the string character by character, maintaining a set to track unique characters encountered so far within the current substring. Whenever a character is found to be already present in the set, it indicates the end of the current substring, and the count of substrings is incremented. The set is then cleared to start a new substring. Finally, the function returns the count of substrings. *** Approach 2: Iterative Approach with Direct Substring Counting *** Similar to Approach 1, this approach also iterates through the string character by character. However, it maintains a count of substrings directly instead of explicitly tracking unique characters. Whenever a character is found to be already present in the set, indicating the end of the current substring, the count of substrings is incremented, and the set is cleared to start a new substring. The function then returns the count of substrings. For a comprehensive understanding and practical demonstration, be sure to watch the entire video.
