JavaObject Oriented ProgrammingProgramming In this article, we will learn how to find the sum of N numbers using recursion in Java. Recursion is when a method calls itself repeatedly until a base condition is me
Let's try to maintain S, the sum of the array throughout one query operation.When acting on an array element A[index], the rest of the values of A remain the same. Let's remove A[index] from S if it is even, then add A[index] + val back (if it is even.)...

编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]print(a
