First, the concept data structure
Way computer storage and organization of data.
Second, why to study
Select different data structures, operating efficiency differences may be caused by relatively large.
Third, the logical structure of data
1, the linear structure
linear structure similar to a line connection element
2, non-linear structural
nonlinear structure can be divided into: the tree structure and FIG. The difference between the tree structure and are: there is no loop tree structure, and there is a loop in FIG. FIG both generalized tree, also includes a linear structure, and further includes a linear generalized tree structure.
