WebDec 4, 2024 · Initialize an empty DP array with 0 of length N plus 1. Update DP [0] with 1. Update DP [1] with -1. Iterate from 0 to N (Let’s say the iterator is i). If DP [i] is 1, Update DP [j] to DP [j] plus 1, If j+JUMP [i]+1 is less than equal to n, Update DP [j+JUMP [i]+1] to DP [j+JUMP [i]+1] minus 1. Else, Update DP [N] to DP [N] minus 1.

Step 2: At a single time, we have 2 choices: Jump one step or jump two steps. We will try both of these options at every index. Step 3: As the problem statement asks to count the total number of distinct ways, we will return the sum of all the choices in our recursive function. magnetic shade for french door
