a) A palindrome is a word, phrase, or sequence that reads the same backwards and forwards. Example: "madam". Write a pseudocode that uses Queue data structure to find whether a given string is a palindrome or not. b) It's a rainy evening and you visit a Montessori school filled with ' n ' kids. The instructor, Mrs. Tina wants to conduct a game and instructs all the kids to form a chain by holding their hands. The kids immediately hold each other's hands and form a chain (each kid has 1 kid to their left and one kid to their right except the first and last kids). Mrs. Tina then starts the game and instructs that she would shout out a number "i and in groups of "i", kids must reverse themselves. Example: [Amirtha, Mani, Sunaina, Ramesh. Nammi] are playing and the instructor shouts out 2. After this round, the kids are in the order. [Mani, Amirtho, Ramesh, Sunaina, Nammi]. Tina would never call out a negative number and she can call out any number less or equal to the positions. Write a pseudocode for this game using an appropriate data structure and mention your complexity using Big-Oh notation. [2+3=5M]
