main.js

// What is the Big O of the below function? (Hint, you may want to go line by line)
function funChallenge(input) {
  let a = 10; // O(1)
  a = 50 + 3; // O(1)

  for (let i = 0; i < input.length; i++) { // O(n) here n -> number of input
    anotherFunction(); // O(n)
    let stranger = true; // O(n)
    a++; // O(n)
  }
  return a; // O(1)
}


// So here big o notaion is
// 3 + n + n + n + n
// BIG O(3 + 4n)
