    Two questions: i)Is the order of jump important , and ii)the starting point is step 1 or step 0? (I am assuming, as of now, that it is step 1) example: one has to go to step 3 starting from 1. possible paths: 1->4 (jump 3) 1->2->4(jump 1,2) 1->3->4(Jump 2,1) 1->2->3->4(Jump 1,1,1,) Now, case 2 and case 3 : are there two considered to be different ? Also, it will be helpful if anyone can kindly explain the statement "the sum of numbers which are formed by first K digit and last K digits of number of ways." with an example.
