// Need to modify the wrapper function to work with a specified timeout (for example, 1 second). // If the "long" function completes within this time - great, return the result. // If not - return an error. The result of the operation in this case does not matter. // // Additionally, measure how long this function took to execute (just log it). // The signature of the wrapper function can be changed.
