1. A sequential search member function of Sorted Type has the following prototype: void Sorted Type::Search( int value, bool & found);

a. Write the function definition as a recursive search, assuming a linked list implementation.

b. Write the function definition as a recursive search, assuming an array based implementation.

2. We want to count the number of possible paths to move from row 1, column 1 to row N, column N in a two-dimensional grid. Steps are restricted to going up or to the right, but not diagonally. The illustration that follows shows three of many paths, if N = 10:

a. The following function, NumPaths, is supposed to count the number of paths, but it has some problems. Debug the function.
int NumPaths(int row, int col, int n)

if (row == n)
return 1;
if (col == n)
return NumPaths + 1;
return NumPaths(row + 1, col) * NumPaths(row, col + 1);

b. After you have corrected the function, trace the execution of NumPaths with n = 4 by hand. Why is this algorithm inefficient?

c. You can improve the efficiency of this operation by keeping intermediate values of NumPaths in a two-dimensional array of integer values. This approach keeps the function from having to recalculate values that it has already figured out. Design and code a version of NumPaths that uses this approach.

d. Show an invocation of the version of NumPaths you developed in part (c), including any array initialization necessary.

e. How do the two versions of NumPaths compare in terms of time efficiency? Space efficiency?
