Sample 1 Explanation • If Michael selects all of the problems, the maximum difficulty would be 10 and the minimum difficulty would be 1. In this case, the difference he wants to minimize would be 9. • If he selects the sublist 6 9, the maximum and minimum difficulties would be 9 and 6 respectively and the difference would be 3. . Note that he can't select 10 9, as that's not a sublist of a.

Q1: Assignment Difficulty
Dan has a list of problems suitable for Assignment 4. The difficulties of these
problems are stored in a list of integers a. The i-th problem's difficulty is
represented by a[i] (the higher the integer, the more difficult the problem).
Dan is too busy eating saltines to worry about Assignment 4 decisions, so he asks
Michael the TA to select at least two problems from the list for the assignment.
Since there are many possible subsets of the problems to consider and Michael
has a life, he decides to consider only sublists (definition follows) of the list of
problems.
To make grading the assignment easier, Michael wants to pick problems that
don't vary too much in difficulty. What is the smallest difference between the
difficulties of the most difficult selected problem and the least difficult selected
problem he can achieve by selecting a sublist of length at least 2 of the original
list of problems?
Definition: A sublist of a list a is any list you can obtain by removing some
(possibly o) elements from the start of a and then removing some (possibly o)
elements from the end of it. (It's like the definition of segment from lecture.).
Filename
Your filename for this question must be q1.py.
Input
The input consists of a single line containing the integers in the list a, separated
by single spaces.
Output
Print a single integer indicating the smallest difference in difficulties Michael can
achieve.
Constraints
2 < len(a) <= 500000
• 1 <<= a[i] <= 10**9
Time Limit
Your program must finish running on any valid input within 3 seconds.

Could you please rewrite the code without the map function? If possible please replace it with for loops or sets/dictionaries. Thanks a lot.
