(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
Computer scientists and mathematicians often use numbering systems other than base 10. Write a program that allows a user to enter a number and a base and then prints out the digits of the number in the new base. Use a recursive function baseConversion (num, base) to print the digits. Hint: Consider base 10. To get the rightmost digit of a base 10 number, simply look at the remainder after dividing by 10. For example, 153 % 10 is 3. To get the remaining digits, you repeat the process on 15, which is just 153 // 10. This same process works for any base. The only problem is that we get the digits in reverse order (right to left). The base case for the recursion occurs when num is less than base and the output is simply num. In the general case, the function (recursively) prints the digits of num // base and then prints num % base. You should put a space between successive outputs, since bases greater than 10 will print out with multi-character "digits." For example, baseConversion(1234,…
2. Sum: a recursive function that computes the sum of integers 1, 2, 3, …., n for a given number n. So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)
6) Write a recursive function to calculate the summation of numbers from 1 to n. For exampleif the user enters 5, your program would add 1+2+3+4+5 and print out the answer 15.7) Write a recursive program to calculate Fibonacci numbers. Use the definition of a Fibonaccinumber where F(n) = F(n-1) + F(n-2). use java to code
Recursive Copy Function Given a string str and number n, write a program that recursively appends a copy of string str n times and returns the resulting string. For example: RecuriveCopy("a", 10)//-> "aaaaaaaaaaa"RecursiveCopy("blah",5)//-> "blahblahblahblahblahblah" Please complete the following function. n is the number of copies to add to str: function RecursiveCopy(str, n) {// your code here} The problem must satisfy the following: You must use recursion. You should end up with n+1 copies of the str total in the output because you are appending additional str copies. Use string literal formatting for the output.
