727B Bill Total Value 
Vasily exited from a store and now he wants to recheck the total price of all purchases in his bill. The bill is a string in which the names of the purchases and their prices are printed in a row without any spaces. Check has the format "name1price1name2price2...namenpricen", where namei (name of the i-th purchase) is a non-empty string of length not more than 10, consisting of lowercase English letters, and pricei (the price of the i-th purchase) is a non-empty string, consisting of digits and dots (decimal points). It is possible that purchases with equal names have different prices.
The price of each purchase is written in the following format. If the price is an integer number of dollars then cents are not written.
Otherwise, after the number of dollars a dot (decimal point) is written followed by cents in a two-digit format (if number of cents is between 1 and 9 inclusively, there is a leading zero).
Also, every three digits (from less significant to the most) in dollars are separated by dot (decimal point). No extra leading zeroes are allowed. The price always starts with a digit and ends with a digit.
For example:

"234", "1.544", "149.431.10", "0.99"and "123.05"are valid prices,

".333", "3.33.11", "12.00", ".33", "0.1234"and "1.2"are not valid.

Write a program that will find the total price of all purchases in the given bill
Input
The only line of the input contains a non-empty string s with length not greater than 1000 — the content of the bill.
It is guaranteed that the bill meets the format described above. It is guaranteed that each price in the bill is not less than one cent and not greater than 106dollars.
Output
Print the total price exactly in the same format as prices given in the input.

非常に面倒な問題で、私のコードは2つの部分に分けられ、第1の部分は配列を確立して入力された文字列の中に現れたすべての数字を保存し、doubleタイプの和をsumに変換します.第2部はテーマの要求に基づいて私たちをテーマの中で要求する奇妙なフォーマットに求めて変換します.ここで分類議論を始める必要があります.sumから整数ですか?小数点はありますか?0ですか?私はそれを
if(sam==0)....else if(sam%100!=0){if(sam>=100) .....else  if(sam>=10)....else...}else{if(sam>=100000)...else ...}
このように書くのはあまり乱れないでしょう...
