It is like gate exam paper more of electronics questions than programming languages. Here the programming language is c and embedded
Compilation stages involve preprocessing, compilation, assembly, linking, and loading.
Preprocessing: Includes expanding macros, handling conditional compilation, and file inclusion.
Compilation: Translates source code into assembly code or machine code.
Assembly: Converts assembly code into object code.
Linking: Combines multiple object files and libraries into a single executable.
Loading: Loads the executable into memory
Bitwise operators are used to perform operations at the bit level on binary numbers.
Bitwise AND (&) - sets a bit to 1 only if both input bits are 1
Bitwise OR (|) - sets a bit to 1 if either input bit is 1
Bitwise XOR (^) - sets a bit to 1 if the input bits are different
Bitwise NOT (~) - inverts all the bits
Left shift (<<) - shifts the bits to the left by a specified number of positions
Right shift (>>) - shifts the bits
Pointers are variables that store memory addresses of other variables in programming languages like C and C++.
Pointers are used to store memory addresses of variables.
They allow direct manipulation of memory locations.
Pointers can be used to pass variables by reference.
Example: int *ptr; ptr = # *ptr = 10; // num now equals 10

RISC stands for Reduced Instruction Set Computing and CISC stands for Complex Instruction Set Computing.
RISC processors have a smaller set of simple instructions, while CISC processors have a larger set of complex instructions.
RISC processors typically execute instructions in one clock cycle, while CISC processors may require multiple clock cycles.
RISC processors rely on optimizing compilers for performance, while CISC...
Interpreter translates code line by line while compiler translates entire code at once.
Interpreter: translates code line by line, slower execution, easier debugging (e.g. Python)
Compiler: translates entire code at once, faster execution, harder debugging (e.g. C++)

The question is asking about how often each character appears in a given string.
Iterate through the string and count the frequency of each character using a hashmap.
Return the hashmap with characters as keys and their frequencies as values.

Tuple is an immutable sequence type in Python that can store multiple values of different data types.
Tuples are defined using parentheses () and separated by commas.
Tuples can be accessed using indexing or slicing.
Tuples are immutable, meaning their values cannot be changed once defined.
Tuples are commonly used for returning multiple values from a function.
Tuples can also be used as keys in dictionaries.
Example: my_tup...
