 Explantion: Perhaps many people like to use recursion mathod, but as I have been practise using Dynamic Programming, 
 						I did it in my own DP way, which is efficient when the dimensions are larger.
 						Again, this problem is similiar to the problem "Pascal' Travel" on Peking University Online Judge. ^-^
 						Everyone no matter his age or sex, he can do DP.
