  2. Search data structure - Wikipedia

    en.wikipedia.org/wiki/Search_data_structure

    However, in a classic array, the array is used to store arbitrary unsorted elements, and hence the exact position of any given element is of no consequence, and insert is carried out by increasing the array size by 1 and storing the element at the end of the array, which is a O(1) operation.

  3. Subset sum problem - Wikipedia

    en.wikipedia.org/wiki/Subset_sum_problem

    Given the two sorted lists, the algorithm can check if an element of the first array and an element of the second array sum up to T in time (/). To do that, the algorithm passes through the first array in decreasing order (starting at the largest element) and the second array in increasing order (starting at the smallest element).

  5. Maximum subarray problem - Wikipedia

    In this case, the array from which samples are taken is [2, 3, -1, -20, 5, 10]. In computer science, the maximum sum subarray problem, also known as the maximum segment sum problem, is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers.

    —, 0, 0, 4, 0, 2, 2, 6, 0, 1, 1, 5, 1, 3, 3, 7. In most applications, the positions of the nearest smaller values, and not the values themselves, should be computed, and in many applications the same computation should be computed for the reversal of the sequence in order to find the following smaller value that is closest in the sequence.

  7. Min-max heap - Wikipedia

    en.wikipedia.org/wiki/Min-max_heap

    Min-max heaps are often represented implicitly in an array; [4] hence it's referred to as an implicit data structure. The min-max heap property is: each node at an even level in the tree is less than all of its descendants, while each node at an odd level in the tree is greater than all of its descendants .

  8. Selection algorithm - Wikipedia

    en.wikipedia.org/wiki/Selection_algorithm

    Therefore, the worst-case number of comparisons needed to select the second smallest is + ⌈ ⁡ ⌉, the same number that would be obtained by holding a single-elimination tournament with a run-off tournament among the values that lost to the smallest value. However, the expected number of comparisons of a randomized selection algorithm can ...

  9. Selection sort - Wikipedia

    en.wikipedia.org/wiki/Selection_sort

    In computer science, selection sort is an in-place comparison sorting algorithm.It has a O(n 2) time complexity, which makes it inefficient on large lists, and generally performs worse than the similar insertion sort.
