Explanation

1. Function Declaration (num_stolbca<Type>):

   • A templated function that takes a pointer to a 2D array (arr), and two constants for dimensions n (number of rows) and m (number of columns).

2. Memory Allocation (ar_d_declaration):

   • Dynamically allocates memory for a 2D array ar_d of size n x m.

3. Initialize ar_d to Zero (array_initialization_2):

   • Initializes all elements of ar_d to zero using nested loops.

4. Comparison and Counting (comparison_loop_1):

   • Compares elements of the input 2D array column-wise and counts occurrences to populate ar_d.

5. Find Maximum Occurrences (find_max):

   • Finds the column (stolb) with the maximum value in ar_d.

6. Cleanup Dynamic Memory (cleanup):

   • Deallocates the memory used by ar_d to avoid memory leaks.

7. Return Result (return_stolb):

   • Returns the column index with the maximum occurrences.
