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. specialized killstreak iron bomber kit
