/*
home work:
1. print the numbers from 1 to 100 with the interval of 10

var result =[]
function odd (arr)
{
    for (var i=0; i<arr.length; i++){
        if (arr[i] % 2 !== 0){
            result.push(arr[i])
        }
    }
    return result
}
console.log(odd([1,2,3,4,5,6,7,8,9,10]));

2. print the number from 10 to 1

var result =[]
var add = function (arr)
{
    for (var i=0; i<arr.length; i++){
        if (arr[i] % 2 !== 0){
            result.push(arr[i])
        }
    }
    return result
}
console.log(odd([1,2,3,4,5,6,7,8,9,10]));

3. print the multiple of 2 until 10

var result =[];
(function (arr)
{
    for (let i=0; i<arr.length; i++){
        if (arr[i] % 2 !== 0){
            result.push(arr[i])
        }
    }
        console.log(result);
}) ([1,2,3,4,5,6,7,8,9,10]);

4. print the number from 100 to 1 with the difference of 10.
var result = []
const odd = (arr) => {
    for(let i=0;i<arr.length;i++){
        if(arr[i]%2!==0){
            result.push(arr[i])
        }
    }
    return result
}
console.log(odd([1,2,3,4,5,6,7,8,9,10]));

5.write a function to print the eligble, Not eligble voters separately from the list
of array [18,17,16,15,10,8,7,9,35,40,86,75,0]. Note: print invalid if the voter age is 0.
