Summary
I participated in the Citadel Securities Online Assessment for a C++ Engineer role. The task involved refactoring complex C++ code to improve its time complexity, specifically solving a problem to find the maximum difference between elements x[i] - x[j] where j <= i within a 1.5-hour time limit.
