I'm wondering why I see such drastic variations in the Time & Space stats for a code that I submit.
Plese note that I'm NOT a premium user. Not sure if this is relevant.

Could someone please help me understand this?

• Here is the problem I've taken as an example : https://leetcode.com/problems/consecutive-characters/

• Sample Solution : https://leetcode.com/problems/consecutive-characters/discuss/723174/Python-3-or-With-Explanation-or-For-Loop-or-No-builtin-Functions

• Same code, but varying run times. Looking for explanation.
