During the month, contributed a cross-language solution for LeetCode problem 3394 to the doocs/leetcode repository, focusing on grid cutting feasibility. Developed and implemented a line sweep algorithm that sorts coordinate points and counts line intersections to determine valid grid partitions, addressing the problem’s requirements. The solution was delivered in Python, Java, C++, and Go, demonstrating versatility in language use and algorithmic design. This work established a reusable pattern for future cross-language problem-solving, streamlining the process of expanding language coverage. The contribution emphasized algorithmic thinking and data structure proficiency, with a focus on maintainability and adaptability for future feature development.
