The task of dog
Above shows a map of a road, which starts from 2 and ends at 18. The dog need to reach to the bone.
Each time the dog pass a number, you have to add it to your current sum. For example: If the dog travelled 2,1 and 4. The sum will be
Is it possible for the dog to reach the end with an exact sum of 100?
Note:
-
The dog is not allowed to pass any number more than once.
-
The dog is only allowed to walk through the black lines.

1 solution
2 + 16 + 17 +18 (= 53) will be numbers the dog will have to pass to reach the bone. So you have to find a path that gives you a total sum of 100 - 53 = 47.
Now if you observe the remaining nodes, you see that the number of odd numbered nodes is even. So we can never get a sum total of 47.
Thus, the answer is a definite NO.
