Basic Index (Loops)

The following code prints the first five whole numbers one line at a time:

for (i in 1:5){
  print(i)
}

Modify this code to accomplish each of the following tasks:

1. Multiply each of the numbers 1 through 5 by 3, then print the result.
2. Use the vector odds <- seq(1, 9, by = 2) and a loop to square these numbers and print them one at a time. Choose a descriptive variable to identify the index values, such as for (odd in odds).

3. Instead of printing the values produced by this for loop, store them in a new vector named output. The following code provides a template for doing this:

   output <- c()
   for (odd in _____) {
     _____ <- _____^2
     output <- c(output, odds_squared)
   }
