Before writing a single line, clarify the input size. Is 10610 to the sixth power ? This tells you if an solution is acceptable or if you must aim for

A solution is only as good as its handling of the "weird stuff." Always test for: (null, empty strings, 0). Single elements (an array of size 1). Large inputs (integer overflows). Duplicates (especially in sorting or searching). The Golden Rule Problem Solving in Data Structures & Algorithms...

Searching in sorted arrays or linked lists (e.g., "Pair with a specific sum"). Before writing a single line, clarify the input size

Look for redundant work. Are you recalculating the same value? (Use Dynamic Programming ). Are you searching linearly? (Use Binary Search or a Hash Map ). 2. The Mental Toolkit (Pattern Recognition) Single elements (an array of size 1)

Most DSA problems are variations of a few core patterns. If you recognize the pattern, the solution follows: When to Use It
