IN C++ Create a task that takes a series of card numbers and checks that their total value is more than 21. If the amount is more than 21, return the truth and if the amount is less than or equal to 21, return false. My card prices are as follows: 2-10 their number. J-K (face cards) are counted as 10. Aces counts as 1 or 11 - play save, so if you give the ace an 11-point make you lose and 1 let you win, then go with 1. Examples overTwentyOne (["2", "8", "J"]) – lie overTwentyOne (["A", "J", "K"]) – - lie overTwentyOne (["5", "5", "3", "9"]) - true

You are hired by a game design company and one of their most popular games is The Journey. The game has a ton of quests, and for a player to win, the player must finish all the quests. There are a total of N quests in the game. Here is how the game works: the player can arbitrarily pick one of the N quests to start from. Once the player completes a quest, they unlock some other quests. The player can then choose one of the unlocked quests and complete it, and so on. For instance, let’s say that this game had only 4 quests: A, B, C, and D. Let’s say that after you complete • quest A, you unlock quests [B, D]. • quest B, you unlock quests [C, D]. • quest C, you unlock nothing [ ]. • quest D, you unlock quest [C]. Is this game winnable? Yes, because of the following scenario: The player picks quest A to start with. At the end of the quest A, the unlocked list contains [B, D]. Say that player chooses to do quest B, then the…
show: Lists the items that the wizard is currently carrying along with the index for each item and the weight of that item. See sample runs below. As shown in the sample this function also prints the total weight of the items along with the max weight limit of 100 lbs. Hint: You can use the sum function in Python to calculate the sum of weights. E.g. sum(weights) will return the sum of all the items in the weights list. grab_item: Add a new item while enforcing the following policy: There is a limit of 4 on the number of items the wizard can carry and limit of 100 lbs on the total weight the wizard can carry. So specifically, if the wizard is already carrying 4 items, print message that “You can't carry anymore items. Drop something first.” And return out of the function. Otherwise prompt the user for the name and the weight of the new item. Next check whether with the addition of the new item, the total weight will exceed the limit of 100 lbs. If so, print a message saying weight…
