Question

PYTHON: This exercise is a variation on "instrumenting"
the recursive Fibonacci program to better understand its
behavior. Write a supporting method that counts how
many times the fib function is called to compute fib (n)
where n is a user input. Hint: To solve this problem, you
need an accumulator variable whose value "persists"
between calls to fib. You can do this by making the count
an instance variable of an object. Create a FibCounter
class with the following methods:
_init_(self) Creates a new FibCounter, setting its count
instance variable to 0.
getCount(self) Returns the value of count.
fib(self, n) Recursive function to compute the nth
Fibonacci number. It increments the count each time it is
called.
resetCount(self) Sets the count back to 0.

Write a Java computer program
Write a java method that receives a reference to an array of integers and then sorts only the non-perfect numbers. if a number is perfect then it must remain in its current location in the array. Notes: 1) You are not allowed to use the Arrays.sort() method or any other ready-made sorting method. 2) You can not define new arrays. Your sorting must be in-place. 3) A number if perfect if the some of its divisors is equal to the number itself. For example the number 6 is perfect because the sum of its divisors is 1+2+3 = 6 while 8 is not perfect because the sum of its divisors is 1+2+4 = 7 which is not equal to 8.
In java i have some code for a method that finds the index of an integer that is passed in thet int is (target) the method also has the array called (array) and the first and last element of the array. also for this method to work the array has to be in descending order "static int find(int [] array, int first, int last, int target)" thats the method with all the variables that are passed to it my guess is that the first if statement just will have a short line that is "return -1;" because since the array has to be in descending order the first element cant be greater then the last element in the array but im confused on the rest because i cant find a way to make them one line codes with the conditions that i have to meet in the comments any help would be aprreaciated

Please answer in python Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one racer has finished the race. Examples: Copy the following if…

Intellij - Java Write a program which does the following: Create a class with the main() method. Take a string array input from the user in main() method. Note: Do not hardcode the string array in code. After the String array input loop, the array should be: words[] = {"today", "is", "a", "lovely", "spring","day", "not", "too", "hot", "not", "too", "cold"}; Print the contents of this array using Arrays.toString() method. Write a method called handleString() that performs the following: Takes a String[] array as method parameter (similar to main method). Loop through the array passed as parameter, and for each word in the array: If the length of the word is even, get the index of the last letter & print that index. Use length() and indexOf() String object methods. If the string length is odd, get the character at the 1st position in the string & print that letter. Use length() and charAt() String object methods.

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false
