Name mangling is a technique used by compilers to give unique names to functions and variables to avoid naming conflicts.
Name mangling is used in C++ to support function overloading.
It is also used in Python to avoid naming conflicts in modules.
Name mangling can make it difficult to access variables and functions from outside the class in which they are defined.
In C++, name mangling can be seen by using the 'nm' comman

Range based map iteration can be done using a for-each loop or iterators.
Use a for-each loop to iterate over the map elements.
Alternatively, use iterators to traverse the map.
The range-based for loop is preferred for its simplicity and readability.
Example: for(auto const& [key, value] : myMap) { //do something with key and value }
Detached threads are independent threads that run separately from the main thread. Joined threads are threads that wait for the main thread to finish.

Joined threads are created using pthread_join() function
Detached threads do not need to be explicitly terminated
Joined threads must be explicitly terminated using pthread_exit() or return statement

No, arithmetic operations cannot be performed on unique pointers.
Unique pointers are used to manage the lifetime of dynamically allocated objects.
They cannot be copied or assigned, only moved.
Arithmetic operations are not defined for pointers, including unique pointers.

Traverse through a matrix of uppercase english alphabets to find a given word. you are allowed to make up to k jumps, and same position can be repeated too.
Compression of 0-1 matrix involves reducing the size of the matrix by storing only the necessary information.
Use run-length encoding to compress the matrix by storing consecutive repeated values as a single value and count.
Identify patterns in the matrix that can be represented more efficiently.
Consider using sparse matrix representation if the matrix has a lot of zeros.
Implement efficient algorithms to compress and de...
