Given a list of numbers, this Python program finds the first unique element in the list. For example, given the input [1, 2, 3, 4, 5, 1, 2 , 3, 4], the output would be 5.
This Python program finds the sum of the even-numbered elements in a list. For example, given the input list [1, 2, 3, 4, 5], the program would output 6.
This technical problem involves implementing a function that takes in a list of numbers and an asynchronous function, and returns a list of the results of the function applied to each number in the list.
