- (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.Write a recursive function called draw_triangle() that outputs lines of '*' to form a right side up isosceles triangle.

- Python only* Use recursive function*. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters here is the specification for concentricCircles function: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. When viewed as nested rings, all rings should have the same thickness. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the outermost circle, and then every other circle in to the center alternates between that color and the other color. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order. Hint: Each function call frame only needs to draw a single circle. Note that you must use the turtleBeads drawDot function to draw each circle Do not use any kind of loop Within the definition of…Python only* Use recursive function*.

If the nonnegative integer is 4, the pattern generated is as follows: **** *** ** * * ** *** **** Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the preceding pattern.
- Write a recursive function named largestDigit that accepts an integer parameter and returns the largest digit value that appears in that integer. Your function should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. You must not use any loops; you also cannot use the string type or any library functions. Your function must be recursive. Complete the following file: largestDigit.cpp 2 // You may use this helper function 3 int max(int a, int b) { return a < b ? b : a; } 4 5 int largestDigit(int n) if((n<0) && (n/10 if(n<0) n = 0)) return n; 8 -n; static int maxi 9 n%10; 0) return maxi; maxi = max(maxi, n%10); return largestDigit(n/10); = 10 if((n/10) 11 12 13 14 15 16 } Submit Calling with Arguments Name Arguments Actual Expected pass largestDigit 135725 7 7 pass largestDigit 111211 2 2 fail largestDigit 100000 1 pass largestDigit 4530021 5 pass largestDigit 7639852 fail largestDigit 76352 6 pass…8. A country has coins of denomination 3, 5 and 10 respectively. Write a recursive function canchange() which returns -1 if it is not possible to pay a value of k using these coins. Otherwise, it returns the minimum number of coins needed to make the payment. For example, canchange(7) will return -1. On the other hand, canchange(14) will return 4 because 14 can be paid as 3+3+3+5 and there is no other way to pay with fewer coins Programming Language:- C1. Write a recursive function that takes a string as an input and returns the reverse of the string. 2.Write a recursive function rec_string that produces the output shown below for the corresponding function calls. Write a main function to test the function. Method call rec_string(‘abcde’), will produce the following output: *ede cde bcde abcde Method call rec_string(‘abc’), will produce the following output: *cbc abc 3. Write a recursive function for Euclid's algorithm to find the greatest common divisor (gcd) of two positive integers. gcd is the largest integer that divides evenly into both of them. For example, the gcd(102, 68) = 34. You may recall learning about the greatest common divisor when you learned to reduce fractions. For example, we can simplify 68/102 to 2/3 by dividing both numerator and denominator by 34, their gcd. Finding the gcd of huge numbers is an important problem that arises in many commercial applications. We can efficiently compute the gcd using the…

I've literally tried to create this program and I have no idea how to make it work. Please help me. Is it possible to explain line by line what the code does?In python. Include docstring. Please follow code requirements as listed below. Write a recursive function named is_subsequence that takes two string parameters and returns True if the first string is a subsequence of the second string, but returns False otherwise. We say that string A is a subsequence of string B if you can derive A by deleting zero or more letters from B without changing the order of the remaining letters. The empty string (which has zero characters) is considered a subsequence of any string (since you can derive it by deleting zero or more letters from any string). You can assume that the only characters in the strings will be lower case letters (though that shouldn't really affect your code). Note: subsequences are different than substrings, since the characters of a subsequence don't have to be consecutive. For example, 'aeiou' is a subsequence of 'faceitious', since all the characters appear in the same order, even though they're not consecutive. You may use…
