Algorithms operate on data structure. Therefore, selection of the best algorithm means selecting the best data structure from whole bunch. The data structures do not add any information to analysis model, but they systematize it in a form which is convenient for algorithms which uses it. Many such data structure contains lists, arrays, stacks, queues, trees etc.
