[交流] Euler 工程 第廿二题: 姓的总分 已有5人参与

%% What is the total of all the name scores in the file?
% 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.
function result = euler22()
tic;
fid = fopen('D:\euler\names.txt');
names = fgets(fid); % 读取全部内容到字符串
fclose(fid);

names = strrep(names,'"',''); % 删除"
namelist = regexp(names,',','split'); % 用逗号分隔
sname = sort(namelist); % 排序

result = 0;
for i=1:length(sname) % 循环
    curname = lower(sname{i}); % 全小写
    curname = curname-repmat('a',1,length(curname)); % 与全a作差
    cursum = sum(curname+1); % 求和
    result = result+cursum*i; % 乘顺序计算score,累加
end
toc;
end
