Question: Write the pseudocode for a recursive quicksort on an array. What is its worst-case time complexity, and why? Suppose you have a MAGIC_MEDIAN function

Write the pseudocode for a recursive quicksort on an array. What is its worst-case time complexity, and why? Suppose you have a MAGIC_MEDIAN function that finds an array's median in constant time. What is the worst-case time complexity of your quicksort now? Suppose you have a QUOTIDIAN_MEDIAN function that finds an array's median in linear time. What is the worst-case time complexity of your quicksort now?
