Positive Integers Assignment | Homework For You
The game of “Jump It” consists of a board with n positive integers in a row except for the first column, which always contains zero. These numbers represent the cost to enter each column. Here is a sample game board where n is 6:
| 0 | 3 | 80 | 6 | 57 | 10 |
The object of the game is to move from the first column to the last column in the lowest total cost. The number in each column represents the cost to enter that column. You always start the game in the first column and have two types of moves. You can either move to the adjacent column or jump over the adjacent column to land two columns over. The cost of a game is the sum of the costs of the visited columns.
In the board shown above, there are several ways to get to the end. Starting in the first column, our cost so far is 0. We could jump to 80, then jump to 57, then move to 10 for a total of 80 + 57 + 10 = 147. However, a cheaper path would be to move to 3, jump to 6, then jump to 10, for a total cost of 3 + 6 + 10 = 19.
Write a recursive solution to this problem that computes the cheapest cost of the game and outputs this value for an arbitrary large game board represented as a list. Because the program can take long time to run on large boards, you can assume that the board size is at most 50 columns. Your program doesn’t have to output the actual sequence of moves, only the cheapest cost of this sequence.
Your program must read input from a text file named input.txt and must send output to stdout (the computer’s screen). The input file consists of a sequence of lines, where each line corresponds to a board. The numbers on a line are the costs to enter the columns on the board. For example, the above board is represented in the input file as
0 3 80 6 57 10
Sample input file is as follows:
0 3 80 6 57 10
0 98 7 44 25 3 5 85 46 4
0 57 59 83 9 42 70
0 20 49 96 53 7 43 77
0 24 17 15 61 49 61 8 65 43 26 99 7 57 97 50 93 6 82 52
The corresponding output is as follows:
19
87
138
186
330
