Answer:
Database environment is created by storing the data and other related components.The input-output action takes place in the database when the reading and writing of the record units of block is to be done to and from disk unit to memory storage.
The database engine is responsible for reading action of the record before entering it to the memory and then stores it. If the data record unit is to be exported to the disk then output action takes place .It also helps in performing indexing ,vacuuming, portioning etc the information Thus, I/O is important for database.
Since you gave kind of a vague question. I'll just go with the basics. Amortized analysis in computer science is basically the study of worst case run times regarding a sequence of operations.
When looking at potential, it is the physicist's method.
phi (initial state) =0 and every state after is larger than 0.
It keeps track of time but relies on states to know where it is.
The equation C +phi (state')-phi(state) is the main equation. C is the time for an operation, "state" is before and "state'" is after.
There are sets of equations that dictate average run time with this.
ex.
phi (H)= 2n-m. n=number of elements, m=size of array.
This equation is used to calculate the time to double the size.
Answer:
arr = [4, 2, 5]
Explanation:
The while loop will remove the array elements from the back.
The internet can be compared to many stuff, such as a world wide web, or a huge box with stuff and you put in what you want and it comes out!
