Answer 1

You can use the below approach

var array = [];
var size = prompt('Enter Array Size'); //Maximum Array size

for(var i=0; i<size; i++) {
    
    //Taking Input from user
    array[i] = prompt('Enter Element ' + (i+1));
}

//Print the array in the console.
console.log("Array Input: "+array.join(','));

let output = [];
    let l = array.length - 1;
    for (let i = 0; i <= l; i++, l--) {
        if (i>=array.length/2) {
            console.log(array[i]);
            break;
        }
        output.push(array[l]);
        output.push(array[i]);
    }

console.log("Resultant Array: "+output.join(','));
