Data Structure

Data Structures & Algorithms - Overview Data Structure is a systematic way to organize data in order to use it efficiently. Following terms are the foundation terms of a data structure. Interface − Each data structure has an interface. Interface represents the set of operations that a data structure supports. An interface only provides the list of supported operations, type of parameters they can accept and return type of these operations. Implementation − Implementation provides the internal representation of a data structure. Implementation also provides the definition of the algorithms used in the operations of the data structure. Characteristics of a Data Structure Correctness − Data structure implementation should implement its interface correctly. Time Complexity − Running time or the execution time of operations of data structure must be as small as possible. Space Complexity − Memory usage of a data structure operation should be as little as possible.
