The height of a tree is defined as the number of edges on the longest path in the tree. The function shown in the pseudocode below is invoked as height(root) to compute the height of a binary tree rooted at the tree pointer root. int height (treeptr n) { if (n == NULL) return -1;   if (n →  left == NULL)        if (n →  right == NULL) return 0;        else return ; \(\boxed{B1}\);     // Box 1 else { h1 = height (n →  left);          if (n → right == NULL) return (1+h1);          else { h2 = height (n → right);          return ; \(\boxed{B2}\)   // Box 2                        }            } } The appropriate expressions for the two boxes B1 and B2 are
Two stock options are available for buying. Each offers a variable rate of return of profit over a period of 10 years. For first 4 years one has an incremental rate of return which increases by 2% per year starting from 3% of the investment and stays constant at 8% for the rest of the period. The second one has a constant annual rate of return throughout and give 10% more return after 10 years. What is the annual rate of return on second option?
Consider the following recursive C function that takes two arguments unsigned int rer (unsigned int n, unsigned int r) { if (n > 0) return (n%r + rer (n/r, r)); else return 0; } What is the return value of the function rer when it is called as rer (513, 2)?
Consider the pseudocode given below. The function DoSomething() takes as argument a pointer to the root of an arbitrary tree represented by the leftMostChild-rightSibling representation. Each node of the tree is of type treeNode. typedef struct treeNode* treeptr; struct treeNode {              treeptr leftMostChild, rightSibling; }; int DoSomething (treeptr tree) {              int value=0;              if (tree != NULL) {              if (tree->leftMostChild == NULL)              value = 1;    else               value = DoSomething(tree->leftMostChild);               value = value + DoSomething(tree->rightSibling);     }               return(value); } When the pointer to the root of a tree is passed as the argument to DoSomething, the value returned by the function corresponds to the 
Consider the following C code segment int f (int x) { if (x<1) return 1; else return ( f{x-1) + g(x) ); } int g (int x) {  if (x< 2) return 2; else return ( f(x-1) + g(x/2)); } Of the following, which best describes the growth of f(x) as a function of x ?
What is the return value of f(p,p), if the value of p is initialized to 5 before the call? Note that the first parameter is passed by reference, whereas the second parameter is passed by value. int f (int &x, int c) {      c = c - 1;       if (c == 0) return 1;       x = x + 1;       return f(x,c) * x; }
