Why can't we always solve problems quickly?
Imagine you're trying to find the best route for a road trip, with many possible paths. You want to save time and avoid traffic jams.
Some problems, like finding the best route, can be solved quickly if there's a simple way to check all options. But others, like NP-complete problems, are like trying to find the best route with no clear shortcuts, making them tough to solve quickly.
Example
Checking every possible route for a road trip (NP-complete problem) takes forever compared to finding the best route using a simple rule (easy problem).
Remember this
The key insight is that some problems are inherently complex and require much more time to solve efficiently than others.
