Web2. if i search 1 (first number) means, its resulting 1 is not found at 0th position for both lower and upper case. 3. if search 9 (last number) means, if there is two 9 , it resulting correctly. It there is only one 9 means, it resulting correctly for lower position. for upper position search its resulting segmentation fault. Why it is :- (

WebFeb 8, 2024 · The binary search, the way it is described above, finds the partition of the array by the predicate f ( M) , holding the boolean value of k < A M expression. In other words, binary search finds the unique index L such that f ( L) = 0 and f ( R) = f ( L + 1) = 1 . It is possible to use arbitrary monotonous predicate instead of k < A M .
