2 ≤ bases ≤ 36, number length ≤ 20
Sample Input/Output
Input: 
1010
2
10
Output: 
10
Explanation

Binary 1010 equals decimal 10

Solution Hints
  • Read carefully: Understand input/output format and constraints
  • Start simple: Think of brute force solution first, then optimize
  • Edge cases: Consider empty inputs, single elements, max constraints
  • Data structures: Choose arrays, hash maps, sets based on problem needs
  • Time complexity: Ensure your solution fits within time limits
  • Test examples: Verify logic with provided sample inputs
