Names scores
Using
names.txt
(right click and 'Save Link/Target As...'), a 46K text file containing over five-thousand first names, begin by sorting it into alphabetical order. Then working out the alphabetical value for each name, multiply this value by its alphabetical position in the list to obtain a name score.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, COLIN would obtain a score of \$938 × 53 = 49714\$.What is the total of all the name scores in the file?
While being fairly comfortable with the zen of Python, Julia is very new to me. Is the following code in line with Julia's vision?
In particular I feel my handling of the dictionary is sub-optimal and especially the way i hard-code remove the parenthesis in names.
Every hint on how to improve the code is welcome.
ALPHABET_INDEX = Dict( letter => index for (index, letter) in enumerate('A':'Z'))
function namescore(name)
return sum(ALPHABET_INDEX[letter] for letter in name[2:end-1])
end
function sort_file(filename)
file = open(filename)
sort(split(readstring(filename),","))
end
function PE_022(filename="p022_names.txt")
total = 0
for (index, name) in enumerate(sort_file(filename))
total += index*namescore(name)
end
total
end
println(PE_022())
