.Initialize ar_d
to Zero (array_initialization_2
):
ar_d
to zero using nested loops.Comparison and Counting (comparison_loop_1
):
ar_d
.Find Maximum Occurrences (find_max
):
stolb
) with the maximum value in ar_d
.Cleanup Dynamic Memory (cleanup
):
ar_d
to avoid memory leaks.Return Result (return_stolb
