What is the time and space complexity of Implement Curry?

Time complexity: O(1) per partial call. Space complexity: O(n) where n is the number of arguments.

Solution Guide: Implement Curry

Approach

Return a recursive wrapper function that accumulates arguments across calls. Compare the accumulated argument count against the original function's arity (fn.length). When enough arguments are collected, invoke the original function; otherwise, return a new function that continues collecting.

Why It Works

Checking args.length against fn.length determines when all required parameters are present, and the rest/spread operators naturally accumulate arguments across successive partial applications.
