Strings A string stores textual data. Defined using single or double quotes. integer_var = 100 string_var = "sample text" Output Formatting employee = 'Bob' job_title = 'Developer' office = 'Innovation Hub, Floor 3' print('-------------------') print(f"Name: {employee}") print(f"Position: {job_title}") print(f&qu ...

Built-in Methods for Numeric Types (int and float) The int() and float() functions are used for type creation and conversion. # Type definition age = 10 # Equivalent to age = int(10) salary = 3000.3 # Equivalent to salary = float(3000.3) # Type conversion s = '123' res = int(s) # Converts string of integers to int print(res, type(res)) # O ...

String Operations Whitespace Removal text = '\n x yz \n' print(text.strip()) # Removes leading and trailing whitespace and newlines print(text.rstrip()) # Removes trailing whitespace only print(text.lstrip()) # Removes leading whitespace only Substitution print(text.replace('x', 'X')) # Replaces all 'x' characters with 'X' print(tex ...

sizeof Operator The sizeof operator represents a compile-time unary operator that yields the size in bytes occupied by an object or type. The result is a value of type size_t, which is an unsigned integral type capable of representing the size of any object in memory. Key characteristics of size_t: Machine-independent unsigned type Large enoug ...

String Reversal String reversal serves as a fundamental operation in string manipulation. While most programming languages provide built-in reverse functions, understanding the underlying mechanism is crucial for technical interviews. The approach uses two pointers starting from opposite ends of the string. These pointers move toward the center ...

Given a array of distinct integers, find all pairs with the smallest absolute difference and return them in ascending order. function findMinAbsDifference(arr) { let result = []; arr.sort((a, b) => a - b); let minDiff = Infinity; for (let i = 0; i < arr.length - 1; i++) { let diff = arr[i + 1] - arr[i]; if ...

Data Types in Java Java categorizes data types into primitive and reference types. Primitive types include eight basic categories: byte, short, int, long, float, double, char, and boolean. Reference types encompass classes like String. Java ensures consistent memory allocation across platforms, with int always occupying four bytes. Unlike C, Ja ...

Iterators provide a mechanism to access elements within containers like std::vector and characters within std::string. While std::vector and std::string offer common functionalities, only std::vector supports direct index access. Most standard library containers leverage iterators for element traversal. Iterators function similarly to pointers, ...

Conditional Statements if Statement The syntax for an if statement is: if condition: code_block Execution flow: When the if condition evaluates to True, the code block is executed. If the condition is False, the code block is skipped, and the program continues execution. Notes: 1. Each condition must be followed by a colon (:) to in ...

In C, a string is a sequence of characters enclosed in double quotes. Every string literal is implicitly terminated by a null character '\0', which marks the end of the string. If this terminator is missing in a manual built character array, functions like printf("%s", ...) will continue reading memory beyond the array until encounter ...
