- Please help I need help making this function bool power_of_two( unsigned n) and I dont understand itWrite code to complete raise_to_power). Note: This example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(0, would be more common. Sample output with inputs: 4 2 4^2 = 16 344614.2214230.qx3zqy7 1 def raise_to_power (base_val, exponent_val): if exponent_val result_val 2 0: == = 1 4 else: result_val base_val * Your solution goes here ... = 6. 7 return result_val 9 user_base 10 user_exponent int (input ()) int (input ()) = = 11 12 print ('{}^{} {}'.format (user_base, user_exponent, raise_to_power (user_base, user_exponent))) 134. In addition to the 'cos' pre-defined function, which is found in the "cmath' library, the cosine of an angle 'x' (given in radians), can be estimated using the following infinite series: x? x* cos(x) =1– 2! +...+(-1)" 4! +... (2n)! However, based on the number of terms 'n' used in the above series, an ERROR MARGIN (EM) can be found between the estimated value and the value returned by the pre-defined function "cos'. Write a C++ program, which does the following: 1. Allows the user to enter the value of the EM, which must be between 0 and 0.0010. A suitable error message should be displayed if EM is entered outside this range and the program must terminate 2. Reads a list of angles (given in degree) from a text file (see angles.txt). The program should only accept angles between 0 and 180°. When invalid angle is read from the file, an error message should be displayed (see the sample output) 3. Includes THREE user-defined functions to perform the following tasks: a. Convert the angle…
- Write a function that takes 4 Inter gets (num1, den1,num2,den2) as parameters which represent the rational numbers num1/den1, num2/den2 and returns the division of these two fractions. A/B ÷ C/D = A/B × D/C = AD/BC • den 1, den2, and num2 can not be zero. • use multiplication_rat function.Data Structures and Algorithms in C/C++ a) Implement the addLargeNumbers function with the following prototype: void addLargeNumbers(const char *pNum1, const char *pNum2); This function should output the result of adding the two numbers passed in as strings. Here is an example call to this function with the expected output: /* Sample call to addLargeNumbers */ addLargeNumbers("592", "3784"); /* Expected output */ 4376 b) Implement a test program that demonstrates adding at least three pairs of large numbers (numbers larger than can be represented by a long). c) (1 point) Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant.Python: How do I create a recursive function asterisk with both recursive and base cases? so for n=3, you would have below; *** ** * code that I have: for i in range(n): print("*",end="")
- Midterm Practice Problems 1. Use recursion to write a function count_ones that returns how many Is there are in a number n when represented in decimal (base 10). For example, 1231 has two 1s. You can assume that n is nonnegative and at most 9 digits long. Do not use global (or static) variables. In main perform at least three tests of count_ones and use assert to check that the returned value is correct. Your function should have the following prototype: // count_ones (n) returns the number of is in the decimal representation of n // requires: 0 <= n < 10^9 int count_ones (int n);Write code to complete raise_to_power(). Note: This example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(), would be more common.Sample output with inputs: 4 24^2 = 16 def raise_to_power(base_val, exponent_val): if exponent_val == 0: result_val = 1 else: result_val = base_val * ''' Your solution goes here ''' return result_val user_base = int(input())user_exponent = int(input()) print('{}^{} = {}'.format(user_base, user_exponent, raise_to_power(user_base, user_exponent)))In loop functions.py, define a function named permutations that takes two paramters, n and r, in that order. This function returns the number of different permutations of length r from set of size n. Essentially to calculate these permutations, the function should compute the product (n - r+1)*(n-r+2)*(n-r+3)*...*(n-2)*(n-1) or n!/(n-r)!. No if statements or built in math functions should be used. For or while loops are best reccomended.

The geometric mean g of n numbers x; is defined as the nth root of the product of x;: g=Vx1x2X3•…Xn (This is useful, for example, in finding the average rate of return for an investment which is something you'd do in engineering economics). If an investment returns 15% the first year, 50% the second, and 30% the third year, the average rate of return would be (1.15*1.50*1.30)") Compute this.Write code to complete raise_to_power(). Note: This example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(), would be more common.Sample output with inputs: 4 24^2 = 16 def raise_to_power(base_val, exponent_val): if exponent_val == 0: result_val = 1 else: result_val = base_val * Your solution goes here return result_val user_base = int(input())user_exponent = int(input()) print('%d^%d = %d' % (user_base, user_exponent, raise_to_power(user_base, user_exponent)))Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. 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.
