Problem Number

649

Problem Summary

The problem number 649 in the LeetCode-75 curated list is called "Dota2 Senate". It is categorized as a medium-level problem and falls under the queue category. The problem involves simulating a game between two teams using a queue data structure. The key pitfalls in solving this problem include handling the order of the players in the queue and efficiently simulating the banning process.

Solution Summary

The best solution for problem number 649 in the LeetCode-75 curated list involves using a queue data structure. The problem involves rearranging a string according to a specific set of rules. To solve this problem, we can iterate through the string and maintain a queue to store the characters. Whenever we encounter a character that should be moved to the end of the string, we enqueue it. After processing all the characters, we can reconstruct the string by dequeuing the characters from the queue. This solution has a time complexity of O(n), where n is the length of the string.
