说是旋转打印矩阵其实是一圈一圈打印，最终结果表现为旋转的样子。

源代码：

public class spiralOrderPrint {


    public void printEdge(int[][] m,int tR,int tC, int dR,int dC){
        if(tR == dR){
            for(int i = tC; i<=dC;i++){
                System.out.print(m[tR][i] + " ");
            }
        }else if(tC == dC){
            for(int i = tR; i <= dR;i++){
                System.out.println(m[i][tC]+ " ");
            }
        }else{
            int curC = tC;
            int curR = tR;
            while(curC != dC){
                System.out.println(m[tR][curC]+" ");
                curC++;
            }
            while(curR != dR){
                System.out.println(m[curR][dC]+" ");
                curR++;
            }
            while(curC != tC){
                System.out.println(m[dR][curC]+" ");
                curC--;
            }
            while(curR!=tR){
                System.out.println(m[curR][tC]+" ");
                curR--;
            }
        }
    }
