x = 3.5
print(float(int(x)))
```

2 more students C and D have come up as competitors to the Forum Leaderboard top scorers. You have to save all the information in these four vectors in a combined vector and combined data frame.

B_upvotes <- c(2, 1, 3, 4, 2, 4)

C_upvotes <- c(3, 2, 3, 4, 6, 2)

D_upvotes <- c(4, 2, 5, 3, 3, 1)
