Suppose we have a balanced binary search tree T holding n numbers. We are given two
numbers L and H and wish to sum up all the numbers in T that lie between L and H. Suppose
there are m such numbers in T. If the tightest upper bound on the time to compute the sum is
O( na logb n + mc logd n ), the value of a + 10b + 100c + 1000d is _______.

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?4

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 Questions Asked from Trees (Marks 2)
