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 .
