Днес, докато търсех допълнителните упражнения за масиви попаднах на една задача от 2017г , която е отпаднала в сегашните курсове на C# Fundamentals: https://judge.softuni.bg/Contests/Practice/Index/422#3  Стори ми се доста интересна и реших да я направя, но получих 0/100 за жалост. Мисля, че проблема ми е отново при принтирането на минутите и секундите след изчисляването на сумата от числата на получения телефонен номер, тоест от получената сума на числата трябва да получим минути и секунди. Мисля, че този път не е проблема в MonoDevelop. Моля, ако някой може да погледне последните три реда от кода ми, защото само те не излизат правилно в аутпута и като цяло метода sum(). https://pastebin.com/ynfGYjzD

While I was searching today for additional exercises about arrays  I stumble upon one exercise from 2017, which is not included today in C# Fundamental module: https://judge.softuni.bg/Contests/Practice/Index/422#3 I have decided to give it a try, but unfortunately I scored 0/100. I think the problem is in my print method for minutes and seconds after calculate the sum of digits in given phone number. Exactly from current sum of digits  we have to print minutes and second for call duration. I think this time the root of problem is not a MonoDevelop. Can somebody please help me out and give me feedback why my code is not working, I will be very grateful. I think the problem is in the last three lines in my code and in sum().

3. Phonebook-previous problem

You will be given an array of phone numbers (strings) and an array of names (strings). After which, you will be given strings on new lines, until you receive the command “done”. Find the numbers, which correspond to the names and print them on the console in the following format:

• {name} -> {number} // (this line is not included in my task)

A number corresponds to a name when it’s located on the same position as its corresponding name in both arrays.

4.* Phone- my problem

This is an upgrade of the previous problem. Implement the phonebook functionality from the previous problem with this additional functionality:

• call {number/name} -> print “calling {name/number}…”

  • If the sum of the digits (ignore other characters) of the number is odd, print “no answer”.

  • If the sum of the digits (ignore other characters) of the number is even, print “call ended. duration: {duration}”. The duration is calculated from the sum of the digits in the format “mm:ss”

• message {number/name} -> print “sending sms to {name/number}...”

  • if the difference of the digits (ignore other characters) of the number is odd, print “busy”

  • if the difference of the digits (ignore other characters) of the number is even, print “meet me there”

Output:

Output in Judge: 0/100

calling Nakov...
call ended. duration: 09:12
calling 0888123456...
no answer
sending sms to +359886001122...
