a. The colon operator will create a sequence of integers in order. It is a special case of the function seq() which you saw earlier in this assignment. Using the help command seq to learn about the function, design an expression that will give you the sequence of numbers from 1 to 10000 in increments of 372. Design another that will give you a sequence between 1 and 10000 that is exactly 50 numbers in length.

b. The function rep() repeats a vector some number of times. Explain the difference between rep(1:3, times=3) and rep(1:3, each=3).
