Solution

The text you provided seems to be instructions for a program that handles a card flipping game. Here's a step-by-step breakdown:

  1. The program should first prompt the user to enter an integer. This integer should represent a valid index of an unflipped card. The prompt should look like this: "Enter an unflipped card in [0, last_index_of_data_member_values]: ".

  2. If the user enters an integer that is not a valid index (i.e., the integer is negative or larger than the last index of the data member values), the program should print the following prompt: "input is not in [0, last_index_of_data_member_values]. Re-enter: ".

  3. If the user enters the index of a card that has already been flipped, the program should print out the following prompt: "The card is flipped already. Re-enter: ".

  4. If the user's previous input was not valid (either because it was not a valid index or because the card at that index had already been flipped), the program should allow the user to re-enter a new input.

This process should continue until the user enters a valid input.

Sita has a collection of cards represented as an array. She wishes to add a new card to her collection, specifically placing it in the second position within this array. Develop a program that will enable Sita to insert the new card at the second position (The value of the position starts from 1).Input format :The first line of input is an integer n as input, representing the number of cards in Sita's collection.The second line of input consists of the n space-separated integers cards[i], representing the values of each card in her collection.The third line of input is an additional integer, insertValue, representing the value of the new card to be inserted at the second position.Output format :The output displays a single line of n+1 space-separated integers in the updated collection of cards.

Imagine that you are working at Income Tax Department, and you have been assigned the task of determining whether a given PAN card number is valid or not. If it is not valid, you should inform the user which character at position "x" is not valid. In this case, "x" corresponds to the index of the first invalid character.To qualify as a valid PAN number, it must meet the following conditions. 1.    It should be ten characters long.2.    The first five characters should be any upper-case alphabets.3.    The next four-characters should be any number from 0 to 9.4.    The last character should be any upper-case alphabet.5.    It should not contain any white spaces.Input:StringOutput:Valid or Noty at position x is not-valid (if not-valid)Eg: Input:BNZAA2318JOutput: ValidEg: Input:2NZAA2318JOutput: Not2 at position 0 is not-valid
