while it is good solution with O(n) complexity, we do not need to import defaultdict, use {} instead --> count = {}

For those still confused about the problem description, I'll try to explain it in simpler terms.

Imagine a water bottle with a 100% capacity (regardless of its actual volume in milliliters). Let's say that every day, 10% of the water in the bottle evaporates. The question is: on which day will the remaining capacity of the bottle reach a certain threshold?

Example

Given:

Capacity = 100%
Evaporation per day = 10%
Threshold = 10%

Find:

On which day will the remaining capacity of the bottle reach the threshold?

Example calculation:

1. Remaining capacity (%) on the first day = 100 - 10% = 100 - 10 = 90%. Does it reach the threshold? 90 <= 10? No.
2. Remaining capacity (%) on the second day = 90 - 10% = 90 - 9 = 81%. Does it reach the threshold? 81 <= 10? No.
3. Continue the calculation until the remaining capacity reaches the threshold...

Im interested with this solution, yet im not understand tho :D

can you please explain the flow please
