Here is Hackerrank Simple Array sum solution in Python, Java, C++, C and Javascript - https://programmingoneonone.com/hackerrank-simple-array-sum-problem-solution.html

public static int simpleArraySum(List ar) { int sum=0; for(int i=0;i

return sum;
}

}

public static int simpleArraySum(List ar) { // Write your code here int sum=0; for(int i=0;i

return sum;
}

}

def simpleArraySum(ar): return sum(ar)

if name == "main": n = int(input().strip()) ar = list(map(int, input().split())) print(simpleArraySum(ar))

Rust

fn simple_array_sum(ar: &[i32]) -> i32 { let mut counter = 0;

for i in ar {
    counter += i;
}

counter
