Using atext file containing over five-thousand first names, and you will calculate a score for each name. Begin by reading the names from the file and sorting them in alphabetical order. Then, you will compute an alphabetical value for each name where A is 1, B is 2, C is 3 and so on. The alphabetical value of a name is just the sum of the values of the letters in the name. To compute the name-score for a name, you simply multiply this alphabetical value by its position in the sorted list.
For example, when the list is sorted into alphabetical order, COLIN, which is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list.
So, the name-score for COLIN would be 938 * 53 = 49714. What is the sum total of all the name-scores in the file?
