fast way to find most common value across columns dataframe
...can parse one row at the time and find the
most common character (apart for ties...). But I think this will be

Is there a way to run it more efficiently?
Thank you
```
V = c("A", "B", "C", "D")

col_03 = sample(V, 10, replace = TRUE, prob = NULL),
col_04 = sample(V, 10, replace = TRUE, prob = NULL),
col_05 = sample(V, 10, replace = TRUE, prob = NULL),
