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.
