Question
![### Understanding Admissible Heuristics in A* Search
**Definition of Admissible Heuristic:**
An admissible heuristic is one that never overestimates the true value.
**Query 1:**
Is 0 (zero) an admissible heuristic?
**Consideration with Zero:**
If 0 were used as a heuristic in A* search, it would effectively become a uniform-cost search, which tends to find the shortest path without the heuristic guidance.
**Query 2:**
If we used the heuristic "how many letters are in the city name," would A* search be guaranteed to find the shortest path?
