Many developers start solving a problem by immediately writing code.
Strong problem solvers take a different approach.
They pause and think about the structure of the problem first.
- What are the constraints?
- What data structure fits the problem?
- Can repeated work be avoided?
- What edge cases might break the solution?
Answering these questions often reveals the right approach.
Consider a problem where you need to find two numbers that sum to a target.
A brute force solution checks every pair.
But if you think about the constraints, you realize a hash map can reduce the time complexity.
Brute Force: O(n²)
Optimized Approach: O(n)
The difference comes from thinking about the structure before coding.
Coding is often the final step.
The real challenge is understanding:
- constraints
- data relationships
- possible abstractions
- trade-offs
Good engineers don't just write code.
They model the problem first.
