1. Create a table of dimension n+1*m+1 where n and m are the lengths of X and Y respectively. The first row and the first column are filled with zeros.
2. Fill each cell of the table using the following logic.
3. If the character corresponding to the current row and current column are matching, then fill the current cell by adding one to the diagonal element. Point an arrow to the diagonal cell.
4. Else take the maximum value from the previous column and previous row element for filling the current cell. Point an arrow to the cell with the maximum value. If they are equal, point to any of them.

1. Declare two variables, say x and y.
2. Run a loop for x and y from 1 to the max of x and y.
3. Check that the number divides both (x and y) numbers completely or not. If divides completely store it in a variable.
4. Divide the stored number.

Deadlock is a situation when two or more processes wait for each other to finish and none of them ever finish. Consider an example when two trains are coming toward each other on the same track and there is only one track, none of the trains can move once they are in front of each other. A similar situation occurs in operating systems when there are two or more processes that hold some resources and wait for resources held by other(s).

You need to write code to implement a Vending machine that has a bunch of products like chocolates, candy, cold-drink, and accept some coins like Nickle, Dime, Quarter, Cent, etc. Make sure you insert a coin, get a product back, and get your chance back. Also, write the Unit test to demonstrate that these common use cases work. If you get stuck you can read my two-part articles (part 1 and part 2) about solving these classical system design questions.

A checkpoint is like a snapshot of the DBMS state. Using checkpoints, the DBMS can reduce the amount of work to be done during a restart in the event of subsequent crashes. Checkpoints are used for the recovery of the database after the system crash. Checkpoints are used in the log-based recovery system. When a system crash we need to restart the system then at that point we use checkpoints. So that, we don't have to perform the transactions from the very start.

I have several strengths namely – I am patient, committed, honest, and self-motivated.
