Append to a Mutable Default List
In this exercise, you are to define a function called
mutable_default_argument. The function will take two parameters: an integer n and a list lst that defaults to an empty list.The function should append the integer
n to lst and return lst.The first line of the input contains a single integer
m, the number of times the function will be called. Each of the next m lines contains a single integer n, the number that will be appended to the list.The output should contain
m lines. Each line should be a list, representing the state of lst after each function call.Input | Output |
