Below is C code and Python code for an algorithm. C code: 1: void foo( int n, int A, int B, int C ) { 2: if( n==1 ) { 3: printf("%d to %d\n",A,B); 4: return; 5: } 6: foo( n-1, A, C, B ); 7: printf("%d to %d\n",A,B); 8: foo( n-1, B, C, A ); 9: } Python code: 1: def foo(n , A, B, C): 2: if n==1: 3: print(A, "to", B) 4: return 5: 6: foo(n-1, A, C, B) 7: print(A, "to", B) 8: foo(n-1, B, C, A) Let Hn be the number of times the printing function is executed. Assume n ≥ 1. Give a recurrence equation and an initial value for Hn and solve it. Note, you do not need to know what the code is doing to answer this question.

A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1)   The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:   a + bi   +   c + di  =  (a+c) + (b+d)i    (addition) a + bi   −  (c + di) = (a−c) + (b−d)i   (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i   (multiplication) (a + bi) / (c + di)  = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2)   (division)   You can obtain the Absolute Value for a complex number using the following formula: |a + bi|  =  √(a2 + b2)   A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.   (1) Design a class named Complex for representing complex numbers Include…
