WebAug 27, 2024 · Let us recall the definition of big-O notation. If a function g(n) = O(f(n)), this implies that there exists two positive constants n0 and c, such that for all n > n0, 0 ≤ g(n) ≤ c f(n) Hence, it follows that O(n) is equivalent to O(n/2), as n is just n/2 multiplied by a constant factor, which in this case is 2. costway multipurpose steam cleaner
