WebIn this chapter, you will learn about the fundamental elements of the data structure. Characteristics of Data Types in Data Structure The data type chooses the set of values to which a constant will belong and which may be assumed by a variable or an expression within a program, or which may be produced by an operator or a function. WebA stack is a linear data structure in which all the insertion and deletion of data or you can say its values are done at one end only, rather than in the middle. Stacks can be implemented by using arrays of type linear. The stack is mostly used in converting and evaluating expressions in Polish notations, i.e.: Infix. Prefix.

WebThe selection is a straightforward process of sorting values. In this method, to sort the data in ascending order, the 0 th element is compared with all other elements. If the 0 th element is found to be greater than the compared element, the two values get interchanged. In this way after the first iteration, the smallest element is placed at 0 ... WebInsertion sort is a to some extent an interesting algorithm with an expensive runtime characteristic having O (n2). This algorithm can be best thought of as a sorting scheme which can be compared to that of sorting a hand of playing cards, i.e., you take one card and then look at the rest with the intent of building up an ordered set of cards ...
