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. WebAlgorithms Running time of binary search Google Classroom 32 teams qualified for the 2014 World Cup.

Let's say the size of array is n. Then, in m operations of halving the search space, the size of the array search space becomes n/2^m. When it becomes 1, we have found our element. So equate it to 1 and solve for m.
