OUTPUT:

$$$ MERGING TWO LIST USING ARRAY $$$

Enter the size of the first array:4
Enter first sorted array elements:    12    23    35    47

Enter the size of the second array:3
Enter second sorted array elements:    27    68    77

Merging of two sorted array is:    12       23      27      35      47      68     77
