Reverse every word in a string

Short summary

A tutorial on reversing the order of words in a string while removing extra spaces. Two approaches are presented: a brute force method using string splitting (O(N) time, O(N) space) and an optimized two-pointer right-to-left traversal that collects words on-the-fly. The optimized approach avoids creating intermediate arrays by extracting complete words during reverse traversal.

• •Two approaches: brute force (split/join) and optimized (two-pointer traversal)
• •Both achieve O(N) time complexity; optimized version avoids intermediate arrays
• •Educational content for coding interviews and algorithm mastery
