Write HASKELL definitions for the following functions: 1. order
a b c: returns a ternary tuple (tuple with 3 parts) of a, b and c
such that the first element is less-or-equal the second, and the
second is less-or-equal the third element. For example, order 4 2 3
should return (2,3,4). 2. fltr f lst: returns the list consisting
of members of lst that make the function f return True when applied
to it. For example, fltr even [1,2,2,5,8,4] should return
[2,2,8,4]. f can be any function that takes one parameter of the
same type as list elements. 3. compute lst: lst is a list of pairs
of numbers, and the anwser is a list formed as follows – if the
first component is smaller than the second one, then their
multiplication is in the resut. Otherwise, their addition is in the
result. 1. Example 1: compute [(2,3),(8,4),(4,6)] should return
[6,12,24]. 2. Example 2: compute [(8,7),(1,1),(4,5),(2,5)] should
return [15,2,20,10]. 4. eliminate lst: returns a list, obtained
from lst, such that a is in the result only if it is smaller than
the next element that follows it in lst. For example, eliminate
[4,3,6,5,7,9,6] should return [3,5,7]. Note that the last element
of lst will never be in the result, because there is no other
element after it. (hint: use the pattern (x:(y:t)) to access the
first and second elements in front of the list. Or you can use head
and tail functions.) 5. gpa lst: computes the gpa in a given
semester, given a list of (course,credit,grade) tuples. An ‘A’
counts as 4, ‘B’ counts as 3, ‘C’ counts as 2 and ‘D’ counts as 1.
Example: gpa [(“cmse318”,4, ‘A’), (“math163”,3, ‘C’)] should return
3.14 ((4*4+2*3)/7). 6. howmany elem a_list: returns how many elems
are in a_list. For example, howmany 'b' ['a', 'b', 'c', 'b', 's']
should return 2. 7. pair_lists list1 list2: returns a list of
pairs, where the first component of a pair in position i is in
position i of list2 and the second component of a pair in position
i is in position i of list1. For example, pair_lists [3,4,5]
[10,20,30] should return [(10,3),(20,4),(30,5)]. You can assume
that the two lists have the same size. 8. classify_g n: returns a
letter grade based upon a numeric grade, according to the following
schema: n>=90 'A', 80=90 'A', 80<=n<=89 'B',
70<=n<79 'C', otherwise 'D'. For example, classify_i 87
should return 'B'. Define classify_i with the if expression to
implement this function. 10. first_odds n: returns a list of the
first n odd numbers. For example, first_odds 5 should return
[1,3,5,7,9].
