You can think of it as improved version f selection sort, where it divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region by extracting the largest element and moving that to the sorted region. The ComparatorChain calls each Comparator in sequence until either 1) any single Comparator returns a non-zero result (and that result is then returned), or 2) the ComparatorChain is exhausted (and zero is returned). this request, Amazon S3 returns the IsTruncated element with the value set to Heres pseudocode representing Linear Search in Java: It is a brute-force algorithm.

What are Java Keywords and reserved words? If you know that Ord A, and know how to transform B to A (call that transformation function f), then you can also have Ord B. As you can understand from the code, the insertion sort algorithm removes one element from the input data, finds the location it belongs within the sorted list and inserts it there. In hashing, the large keys are converted into small keys by usinghash functions. Next, to filter records based on our two conditions, we're using the anyMatch predicate, inside which we have combined all the given conditions.
