<br>
oke, so use recursion. No problem. <br>

<br>
mapM_ is not explained in the first 5 chapters of Craft of
functional programming,<br>
<br>
Can not both or one of the two be done with list comprehension
because all former exercises uses list comprehension <br>

I have this exercise :<br>
<br>
Define a function<br>
fibTable :: Integer -> String<br>
which produces a table of Fibonacci numbers. For instance,
the effect of putStr<br>
(fibTable 6) should be<br>
n fib n<br>
0 0<br>
1 1<br>
2 1<br>
3 2<br>
4 3<br>
5 5<br>
6 8<br>
<br>
<br>
<br>
1) Can somone give me any pointers how to calculate the fibb
numbers with list comprehension.<br>
I know that the fib numbers are (n -1) + n<br>
<br>
2) Can someone give me any pointers how to write the outcome
of every run<br>
