Question
Write a function min2 to compute the second
smallest of number of an integer list. You may
assume the list has at least 2 numbers and all
numbers are distinct.
min2([1,3,2,5,4]) → 2
Write a function dispnthc to display the n-th
character of a string. You may assume that the
input string is always longer than n.
dispnthc("abcdef", 4) → #"d"
Write a function multin to take a list of three [a,b,c]
and multiplies a by b c times. Function definition
must look like multin(L)! CAN NOT USE
multin(a,b,c). You have to use let-in-end in if-then-
else style NOT @
CAN NOT USE function power(a,b) =a*a*a...,
multin [2,3,5] → [2,6,18,54,162,486]
