ASAP Solution needed / Solution You're given a string of words. You need to find the word "Nemo", and return a string like this: "I found Nemo at [the order of the word you find Nemo]!" If you can't find Nemo, return "I can't find Nemo :(". Examples findNemo ("I am finding Nemo !") → "I found Nemo at 4!" wwwwwwww ➡ "I found Nemo at 1!" findNemo ("Nemo is me") www findNemo ("I Nemo am") wwwwwwwww "I found Nemo at 2!" (Ctrl)
comparison methods that can be useful when working withstrings are StartsWith and EndsWith. These instance methods take a stringas an argument and return True if the instance either starts with or ends withthe string argument.Write two short programs that demonstrate the use of these methods. First, we’ll demonstrate the EndsWith method:

The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…

Note that you can only use recursion to solve Q1 and you cannot use any loop. You are free to add helper methods, but you are not allowed to change the method header.Question 1: Crazy seriesIn this session, you need to implement the crazy series method. In the crazy series, you will be given a starting number. Then, you need to times 2 for each number until the number is greater than 100. After the number is greater than 100, you need to divide 3 until we reach the number is less than 5. Note that the input number must be greater than 0, and you are not allowed to use loop here.For example,crazySeries(10) should return ArrayList [10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(5) should return ArrayList [5.0, 10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(1) should return ArrayList [1.0, 2.0, 4.0, 8.0, 16.0, 32.0, 64.0, 128.0,…
