1. Write a program to calculate the second smallest number in an arbitrary list. For example, if the list is x = [1,2,3,10,23], then the output should be 2. There are many ways to do it, you will receive full marks as long as the program works.
2. Following the previous question, now define a function that takes a list x and an integer n as inputs, and then return the n-th smallest number in list x. For example, if x=[1,2,3,10,23], and n = 4, then func(x,n)=10 because 10 is the 4th smallest number in x.
