String handling
Operations on sequences of characters including concatenation, substring extraction, pattern matching, and manipulation. Strings are fundamental for user interaction and data processing. Different languages provide varying string support from basic arrays to rich libraries. String operations are frequent in programming interviews and practical applications.
Real World
Google's search engine processes billions of string operations daily — when you type a query, it uses substring matching and pattern recognition to find relevant results across trillions of web pages.
Exam Focus
When asked to 'write an algorithm', show string method calls explicitly — don't assume the examiner knows your intent.
