// For answers to be checked the other problems will need to be commented out due to variables aleady be declared


// Problem 1

for (i = 1; i <= 10; i++){
    console.log(i)
}

// Problem 2

for (i = 1; i <= 10; i++) {
    console.log(i * i)
}

// Problem 3

let n = prompt('Please enter positive number');

for (i = 1; i < n; i++) {
    if (i % 2 == 0) {
        console.log(i)
    }
}

// Problem 4

let n = prompt('Please enter positive number')

let m = prompt('Please enter positive number')
    m = Number(m)

let sum = 0

while (n < m) {
     sum += n;

// started alternative method if n was larger than m

// if (n < m) {
//     sum += n;
//     n++;
// } else if (n > m) {
//     sum += n - 1;
//     n--;
// }

// Problem 5

// Problem 6

// Solved without nested loop

// let output = ''

// for (let i = 1; i < 6; i++) {
