"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

Uniform binary search stores, instead of the lower and upper bounds, the difference in the index of the middle element from the current iteration to the next iteration. A lookup table containing the differences is computed beforehand. For example, if the array to be searched is [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11], the middle element () would be 6. In this case, the middle element of the left suba… 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).
