WebFeb 13, 2024 · Step 1: First, read the search element (Target element) in the array. Step 2: In the second step compare the search element with the first element in the array. Step 3: If both are matched, display "Target element is found" … WebThe definitions are independent. Now we can go ahead and formulate asymptotic bounds on runtime functions: upper ( O ), lower ( Ω) or both ( Θ ). We can do either for worst-, best- or any other case. For instance, in binary search we get a best-case runtime asymptotic of Θ ( 1) and a worst-case asymptotic of Θ ( log n). Share.
