Measure Performance of Functions | Dataford Interview Questions

Write a function that measures the performance of other functions.

Implement measure_performance(function_name, args, iterations, clock_values) and return the final result, elapsed time, average time, and iteration count. For deterministic tests, clock_values contains the start and end timestamps; supported function names are add, square, and constant_none.

Constraints

function_name is one of "add", "square", or "constant_none"
args contains the arguments required by the selected function
1 <= iterations <= 10^6
clock_values contains exactly two numbers, with the second value greater than or equal to the first
All function invocations return JSON-compatible values

Function Signature

def measure_performance(function_name, args, iterations, clock_values):
