Developed an Array Restoration Problem Solver for the SSAFYnity/Job-Preparation-Challenge-3rd repository, focusing on automated processing of overlapping-matrix challenges common in competitive programming. The solution was implemented in Java and utilized algorithmic techniques such as backtracking and dynamic programming to efficiently reconstruct original arrays from input matrices. The feature included comprehensive input parsing and output handling, enabling end-to-end automation for similar problem patterns. Emphasis was placed on code quality and performance, achieving a concise implementation with optimized runtime and memory usage. This work established a reusable approach for handling related computational problems, supporting future extensions within the repository’s scope.
