String and Number Manipulation Questions

Focuses on problems that combine string processing and numeric computation. Topics include parsing numeric values from strings, integer and floating point conversion and formatting, base conversions, handling very large integers and precision issues, numeric string validation, interpreting numeric encodings, and performing arithmetic or coordinate transformations derived from string inputs. Also covers algorithmic uses such as digit dynamic programming, modular arithmetic for string encoded numbers, parsing for domain specific formats, and using string operations for tasks like logging, asset naming, and user input handling. Emphasis is on correctness with edge cases such as leading zeros, signs, overflow, locale and formatting, and on combining parsing with subsequent numeric algorithms.
