The Two Sum problem involves finding two numbers in an array that add up to a given target value.
Iterate through the array and store the difference between the target and current element in a hashmap
Check if the current element exists in the hashmap, if yes return the indices
Time complexity can be reduced to O(n) using a hashmap
Reverse a singly linked list and return the reversed list.
Iterate through the linked list and reverse the pointers to point to the previous node instead of the next node.
Use three pointers to keep track of the current, previous, and next nodes while reversing the list.
Update the head of the list to be the last node after reversing.
Find the longest palindromic substring in a given string.
Iterate through each character in the string and expand around it to find palindromes
Use dynamic programming to optimize the solution
Consider both odd and even length palindromes
A carburettor is a device in an internal combustion engine that mixes air with a fine spray of liquid fuel.
Device in internal combustion engines
Mixes air with liquid fuel
Controls the air-fuel mixture for combustion
Commonly found in older vehicles

Deadlock is a situation in which two or more competing actions are each waiting for the other to finish, preventing any of them from progressing.
Occurs in concurrent programming when two or more processes are unable to proceed because each is waiting for the other to release a resource
Can happen in database systems when two transactions are each waiting for a resource locked by the other
Commonly seen in multi-threaded ...
An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one.
AVL tree was named after its inventors Adelson-Velsky and Landis.
Insertions and deletions in AVL trees are performed to maintain the balance factor of each node.
AVL trees are commonly used in database indexing and in-memory database systems.

A PID controller is a type of control loop feedback mechanism used in systems to control the output based on the difference between the desired setpoint and the actual process variable.
PID stands for Proportional-Integral-Derivative, which are the three terms used to describe the controller's actions.
The proportional term responds to the current error, the integral term responds to the accumulation of past errors, and ...
An alternator produces alternating current (AC) while a generator produces direct current (DC).
Alternators are commonly used in modern vehicles to charge the battery and power the electrical system.
Generators are often used in backup power systems or portable power sources.
Alternators have a higher efficiency and are more reliable compared to generators.
Generators require a commutator to convert the AC output to DC, wh...
