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, rightSibiling; 
}; 
Int Dosomething (treeptr tree) 
{ 
    int value =0; 
    if (tree ! = NULL) { 
      If (tree -> leftMostchild = = NULL) 
          value=1; 
    else 
        value = Dosomething (tree->leftMostchild); 
        value = value + Dosometing (tree->rightsibiling); 
    } 
    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

Suppose depth first search is executed on the graph below starting at some unknown vertex. Assume that a recursive call to visit a vertex is made only after first checking that the vertex has not been visited earlier. Then the maximum possible recursion depth (including the initial call) is _________.

Consider a hash table with 100 slots. Collisions are resolved using chaining. Assuming simple uniform hashing, what is the probability that the first 3 slots are unfilled after the first 3 insertions?

Consider the C function given below. Assume that the array listA contains n (> 0) elements, sored in ascending order.

int ProcessArray(int *listA, int x, int n) 
{ 
      int i, j, k; 
      i = 0; 
      j = n-1; 
      do 
      { 
         k = (i+j)/2; 
         if (x <= listA[k]) 
           j = k-1; 
         if (listA[k] <= x) 
           i = k+1; 
      } 
      while (i <= j); 
      if (listA[k] == x) 
           return(k); 
      else 
           return -1; 
}

Which one of the following statements about the function ProcessArray is CORRECT?
