Write a C code to convert a doubly linked list into a circular doubly linked list.
Consider the following relations from a Richfield database. Write relational algebra expression for each statement using symbolic notations.
Books (bid, title, publisher, year)
Students (sid, sname, major, age)
Authors (aid, aname, aaddress)
Borrows (bid, sid, date)
2.2.1 List the title & year of each book. (2)
2.2.2 Find all information about students whose major is Java. (2)
2.2.3 List all students with the books they can borrow. (2)
2.2.4 Obtain all the books published by McGraw-Hill before 2019. (2)
2.2.5 Rename aname in the relation Authors to name.
Denominations - 3
Write a program to find the minimum number of notes required for the amount M. Available note denominations are 500, 50, 10, 1.
Input
The first line is a single integer M.
Output
Print M in denominaitons.
Explanation
Given
M = 1543, it can be written as1543 = 3*(500) + 3*(50) + 0*(10) + 1*(3)Then the output should be
500: 3 50: 0 10: 4 1: 3
Sample Input 1
1543
Sample Output 1
500: 3 50: 0 10: 4 1: 3
Sample Input 2
1259
Sample Output 2
500: 2 50: 5 10: 0 1: 9
Denominations - 4
Write a program to find the minimum number of notes required for the amount M. Available note denominations are 2000, 500, 200, 50, 20, 5, 2, 1.Input
The first line is a single integer M.
Output
Print M in denominations.
Explanation
Given
M = 2257 Then 2257 can be written as
2000 * 1 + 500 * 0 + 200 * 1 + 50 * 1 + 20 * 0 + 5 * 1 + 2 * 1 + 1 * 0So the output should be
2000:1 500:0 200:1 50:1 20:0 5:1 2:1 1:0.
Sample Input 1
2257
Sample Output 1
2000:1 500:0 200:1 50:1 20:0 5:1 2:1 1:0
Sample Input 2
2345
Sample Output 2
2000:1 500:0 200:1 50:2 20:2 5:1 2:0 1:0
