Thanks for the solutions, they make the array-sum concept much clearer! I’m also exploring how to adapt this logic for a real project — specifically on my WordPress site for an Insurance service page. Has anyone here tried reusing these algorithms in practical web applications?

in javascript :

let sum = 0
    for(let i=0 ; i < ar.length ; i++){
        sum += ar[i]
    }
    return sum

public static int simpleArraySum(List ar) {

int sum=0;
for(int i=0;i<ar.size();i++){
    sum+=ar.get(i);
}
return sum;
}

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

def simpleArraySum(ar): finalSum = 0 for i in range(len(ar)): finalSum += ar[i] return finalSum
