| - * Given an array A (index starts at 1) consisting of N integers: A1, A2, ..., AN and an integer B. |
11 |
| - * The integer B denotes that from any place (suppose the index is i) in the array A, |
12 |
| - * you can jump to any one of the place in the array A indexed i+1, i+2, …, i+B if this place can be jumped to. |
13 |
| - * Also, if you step on the index i, you have to pay Ai coins. If Ai is -1, it means you can’t jump to the place indexed i in the array. |
14 |
| - * Now, you start from the place indexed 1 in the array A, |
15 |
| - * and your aim is to reach the place indexed N using the minimum coins. |
16 |
| - * You need to return the path of indexes (starting from 1 to N) in the array you should take to get to the place indexed N using minimum coins. |
17 |
| - * If there are multiple paths with the same cost, return the lexicographically smallest such path. |
18 |
| - * If it's not possible to reach the place indexed N then you need to return an empty array. |

| - Note: |
29 |
| - Path Pa1, Pa2, ..., Pan is lexicographically smaller than Pb1, Pb2, ..., Pbm, |
30 |
| - if and only if at the first i where Pai and Pbi differ, Pai < Pbi; when no such i exists, then n < m. |
31 |
| - A1 >= 0. A2, ..., AN (if exist) will in the range of [-1, 100]. |
32 |
| - Length of A is in the range of [1, 1000]. |
33 |
| - B is in the range of [1, 100]. |
