algorithm complexity

What is a Big O notation? The Big O notation helps identify algorithm efficiency. It can measure computation and memory growth with respect to input. Real-world code example O(n) — Linear Time func containsValue(array: [Int], value: Int) -> Bool { for element in array { if element == value { return true } } return false } O(1) — Constant Time func findFirstElement(array: [Int]) -> Int? { return array.first } Thank you for reading!...
