Здравейте,

Ще може ли някой да изпрати примерно решение на тази задача - Present Delivery от Retake Mid Exam Technology Fundamentals на C#. Нямам никаква идея как да я направя и ще ми е от полза да видя решението при някой друг :) Благодаря предварително! Това е линка за Judge: https://judge.softuni.bg/Contests/Practice/Index/1395#2

Това е условието:

Problem 3. Present Delivery

Santa has limited time to drop at least some presents for each house. Help him with his mission!

You will receive a string with even integers separated by "@" representing each house with its number of members and a series of Jump commands until you receive "Merry Xmas!"

Santa starts at the position of the first house and has to jump by a given length. The jump command will be in format: "Jump {length}".

Each time he jumps from one house to another he drops 2 presents for that house and decreases the needed presents for that house. If Santa jumps on a house which doesn't need more presents (presents = 0) you should instead print "House {houseIndex} will have a Merry Christmas.".

Keep in mind that Santa can have a bigger jump length than the size of the field and if he does jump outside of it he should start from the beginning again.

For example we have a field of size 3 and each house has 6 members. Santa is at the start and jumps with length of 2. He will end up at index 2 and decrease the needed presents by 2 (6 – 2 = 4). Next he jumps again with length of 2 and ends up at index position 1 and again decreases the needed presents.

Input

• On the first line you will receive a string with even integers separated by "@" – houses and their number of members.
• On the next lines until "Merry Xmas!" you will receive jump commands in format: "Jump {length}".

Output

At the end print Santa's last position and whether or not his mission was successful:

• "Santa's last position was {lastPositionIndex}."
• If all members of each house have presents print:
  • "Mission was successful."
• If not print the count of all houses that won't have a Merry Christmas:
  • "Santa has failed {housesCount} houses."

Constraints

• The field can be of size [1…20]

• Each house will have an even number of  members [2 … 10]
• Each jump length will be an integer [1 … 20]
