| Abstract: | To begin with, this paper analyses the connotation of mapping and function definition. Then by establishing the mapping between sets, it presents the solutions to such counting problems as alternate sum, tree, good subset and symmetry number, etc.. Finally it emphasizes the role of mathematical concepts played in solving the theoretical and practical problems. |
