Arrays are a fundamental data structure in Rust that allow you to store a fixed-size collection of elements of the same type. A common operation is to calculate the sum of all elements in an array.
In this challenge, you will implement a function to calculate the sum of elements in an array of integers i32.
You need to implement the function sum_array(arr: &[i32]) -> i32 that takes a slice of integers and returns the sum of all elements.
sum_array function should return the sum of all elements in the array.let arr = [1, 2, 3, 4, 5];
let sum = sum_array(&arr);
assert_eq!(sum, 15); // 1 + 2 + 3 + 4 + 5 = 15.iter() method to iterate over the elements of the array..sum() method to calculate the sum of the elements.pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let total_sum: i32 = arr.iter().sum(); return total_sum;}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut i: i32 = 0; for num in arr.iter() { i += num; } println!("Returning {}", i); arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.into_iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut total = 0; for i in arr{ total = total + i; } return total}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut total = 0; for i in arr{ total = total + i; } return total}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut s = 0; for i in arr { s += i; } return s;}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut sum: i32 = 0; for number in arr { sum += number; } return sum;}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut sum = 0; for i in arr { sum = sum + i; } sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return arr.iter().sum();}pub fn sum_array(arr: &[i32]) -> i32 { arr.iter().sum() // TODO: Implement the function here}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut a: i32 = 0; for i in 0..arr.len() { a += arr[i] } a}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut sum = 0; for item in arr.iter() { sum += item; } sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return arr.iter().sum();}pub fn sum_array(arr: &[i32]) -> i32 { arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { let mut sum = 0; for x in arr { sum += x; } sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut sum: i32 = 0; for element in arr{ sum += element; } sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let mut sum:i32 = 0 ; for number in arr.iter() { sum += *number; } sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return (&arr).iter().sum();}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.into_iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { arr.iter().sum() // TODO: Implement the function here}pub fn sum_array(arr: &[i32]) -> i32 { return arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.into_iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return arr.iter().fold(0, |acc, &item| acc + item);}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return arr.into_iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let sum: i32 = arr.iter().sum(); sum}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { arr.iter().sum()}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here return arr.iter().sum();}pub fn sum_array(arr: &[i32]) -> i32 { // TODO: Implement the function here let sum_of: i32 = arr.iter().sum(); sum_of}
