WebJan 30, 2024 · The worst time complexity of binary search occurs when the element is found in the very first index or the very last index of the array. For this scenario, the number of comparisons and iterations required is logn, where n … 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.
