This one's for the functional peeps out there:

from functools import reduce

def simpleArraySum(ar):
    # Write your code here
    return reduce(lambda x, y: x + y, ar)

By the way, I’m not good at simple array sum problem solutions in Python, but when it comes to gaming like Hailey’s Treasure Adventure Apk, I learn quickly and enjoy the process.

Java 15

This is my code for Java 15 :-

public static int simpleArraySum(List<Integer> ar) {
    int sum = 0;
    for(int i: ar) sum+=i;
    return sum;
}

For Python3 Platform

with python, you can use the sum function. But with other languages, you have to use the loop to calculate the sum

def simpleArraySum(ar):
    return sum(ar)

n = int(input())
ar = list(map(int, input().split()))

result = simpleArraySum(ar)

print(result)

def simpleArraySum(ar): c = 0 for i in ar:
c = c + i return c
