[1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the . Idea is to repeatedly divide in half the portion of the list that could contain the item, until we narrow it down to one possible item. The string is a data type (just like integers) that represents characters rather than just numbers. dsa-intro. - Each step of an algorithm is unique and should be self explanatory. Basic Types of Data Structures (DS) Basically, there are two types of data structures.
