Discussion of Round 2 Problems
Problem 1: The K-Diff Subarray
Participants had to find the maximum subarray of length K in an array, ensuring the difference between the maximum and minimum elements within the subarray was minimal.
Solution
This problem required a more advanced algorithm. I implemented a sliding window approach to efficiently find the maximum subarray. I moved a window of length K through the array, keeping track of the maximum and minimum values within the window.
Problem 2: String Manipulation Maze
In this complex string problem, participants were tasked with transforming one string into another using a series of operations involving character and substring swapping.
Solution
To solve this problem, I started with the first string and applied a series of operations to transform it into the second string. I used a loop to iterate through the characters of both strings concurrently, swapping characters when necessary until the two strings matched.
Problem 3: Pointer Labyrinth
Building upon the concepts introduced in the first round, this problem required complex pointer manipulation to traverse a maze-like data structure and extract specific information.
Solution
The solution to this problem depended on the unique structure and rules provided in the competition. It often involved a combination of pointer manipulation and conditional statements to navigate and extract data from the structure.
While I made progress on these challenges, I did not secure a prize-winning position. Nevertheless, the learning experience was invaluable.
