Implement a function curry(fn) that transforms a function which takes multiple arguments into a function that can be repeatedly called with any number of arguments until all arguments are provided.

The function should:

• Collect arguments from multiple calls.
• Return the final result when the total number of arguments meets the original function's arity.
• Support any number of arguments per call.

Example

function sum(a, b, c) {
  return a + b + c;
}

const curried = curry(sum);
curried(1)(2)(3); // 6
curried(1, 2)(3); // 6
curried(1)(2, 3); // 6
