Binary search algorithm running time

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. WebMay 13, 2024 · Let's conclude that for the binary search algorithm we have a running time of Θ ( log ( n)).
