WebJan 11, 2024 · The Average Case: On average, the target element will be somewhere in the middle of the array. The number of comparisons, in this case, will be N/2. So, the time complexity will be O(N) (the constant being ignored). The Worst Case occurs when the target element is the last element in the array or not in the array. In this case, we have to ... 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.

"WebIn binary search, without doing any analysis, we can see that the array is divided into half its initial size each time. So even in the worst case, it would end up searching only log2n log 2 n elements. Thus, binary search is a O(lgn) O ( lg n) algorithm. We are also going to mathematically see this running time later in this chapter. " - Binary search best worst average case
