// What is the Big O of the below function? (Hint, you may want to go line by line)
function anotherFunChallenge(input) {
let a = 5; // O(1)
let b = 10; // O(1)
let c = 50; // O(1)
for (let i = 0; i < input; i++) { // O(n)
let x = i + 1; // O(n)
let y = i + 2; // O(n)
let z = i + 3; // O(n)
}
for (let j = 0; j < input; j++) { // O(n)
let p = j * 2; // O(n)
let q = j * 2; // O(n)
}
let whoAmI = "I don't know"; // O(1)
}
// Big O = 4 + 7n = O(n)
// 4 constant time
// 7 linear time
