So yesterday, you were given a list of positive and negative numberd and told
to solve the sum-distance from the origin. Good. You've got it!
Today, you're given a list of numbers:
--}
exDir, nums :: FilePath
exDir = "Y2018/M12/D19/"
nums = "nums.txt"
{--
But you notice the numbers are not ... quite! ... in the correct format. The
correct format is:
+<Int> for a positive number, and
-<Int> for a negative number
So, for example, you have:
4887
4127
-6400
9231
-2918
...
but what you need is
+4887
+4127
-6400
+9231
-2918
...
read in the above file then output the file in the correct format.
