1. Make this list with less work:

    [26,25,24,23,22,21,20,19,18,17,16,15,14,
    13,12,11,10,9,8,7,6,5,4,3,2,1]
   

2. Make this string with less work:

    "abcdefghij"
   

3. How do you make a list that starts [8,8,8,8,8 and then goes on forever.

4. What is the signature of the function you used in the previous question?

5. What is the difference between cycle and repeat?

   Possible signature: cycle :: [Int] -> [Int]

   Example: cycle [8,9,11] == ?

6. Write an example showing an equality between cycle applied to something and repeat applied to something.

    cycle __________ == repeat __________
   

7. How do you get the following? Would that change if there were fifty 2’s instead of five?

    [2,2,2,2,2]
   

8. Make this list:

    [(1,10),(2,20),(3,30),(4,40) ... up to ... (9,90)]
   

9. Make this list:

    [(2,23), (2,24), (2,25), (3,23), (3,24), (3,25),
    keep going all the way to (13,23), (13,24), (13,25)]
   

10. Make this list:

    n10 = [(2,23), (3,24), (4,25), ... go until ... (50,71)]
    

11. Find all of the ordered pairs (x,y) from the list n10 above that have y>x*x.
