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
{
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);
}
{
int value=0;
if (tree != NULL)
{
if (tree->leftMostChild == NULL)
value = 1;
else
value = DoSomething(tree->leftMostChild); value = value + DoSomething(tree->rightSibling);
}
return(value);
}
Q. 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
- a)number of internal nodes in the tree.
- b)height of the tree.
- c)number of nodes without a right sibling in the tree.
- d)number of leaf nodes in the tree.
Correct answer is option 'D'. Can you explain this answer?

Consider the pseudocode given below. The function DoSomething() takes ...
The function counts leaf nodes for a tree represented using leftMostChild-rightSibling representation. Below is function with comments added to demonstrate how function works. [sourcecode language="C"] int DoSomething (treeptr tree) { // If tree is empty, 0 is returned int value = 0; // IF tree is not empty if (tree != NULL) { // IF this is a leaf node, then values is initialized as 1 if (tree->leftMostChild == NULL) value = 1; // Else value is initialized as the value returned by leftmost // child which in turn calls for the other children of this node // Using last call "value = value + DoSomething(tree->rightSibling);" else value = DoSomething(tree->leftMostChild); // Add value returned by right sibling value = value + DoSomething(tree->rightSibling); } return(value); }[/sourcecode]

Explanation:
To understand why the value returned by the function corresponds to the number of leaf nodes in the tree, let's analyze the pseudocode step by step.
The function DoSomething() takes a pointer to the root of an arbitrary tree represented by the leftMostChild-rightSibling representation.
Step 1: Initialize a variable "value" to 0.
Step 2: Check if the tree pointer is not NULL. If it is NULL, it means that the tree is empty and there are no nodes. In this case, the function returns 0.
Step 3: If the tree pointer is not NULL, check if the leftMostChild pointer of the current node is NULL. If it is NULL, it means that the current node is a leaf node (a node with no children). In this case, set the value to 1.
Step 4: If the leftMostChild pointer is not NULL, recursively call the DoSomething() function with the leftMostChild pointer as the argument. This will traverse the subtree rooted at the leftMostChild pointer and count the number of leaf nodes in that subtree.
Step 5: After the recursive call, the value variable will hold the number of leaf nodes in the subtree rooted at the leftMostChild pointer.
Step 6: Call the DoSomething() function with the rightSibling pointer as the argument. This will traverse the remaining siblings of the current node and count the number of leaf nodes in each subtree rooted at the siblings.
Step 7: Finally, return the value variable.
Conclusion:
From the above analysis, we can conclude that the value returned by the DoSomething() function corresponds to the number of leaf nodes in the tree. This is because at each recursive call, the function checks whether the current node is a leaf node or not. If it is a leaf node, the value is set to 1. If it is not a leaf node, the function recursively counts the number of leaf nodes in the subtrees rooted at its children. By traversing the entire tree using the leftMostChild-rightSibling representation and counting the number of leaf nodes at each step, the function eventually returns the total number of leaf nodes in the tree.
