Write a C program that places the given integer values into a B - tree. The level of the B - tree is 3. The number of integers is not known beforehand. After placing the numbers into the B - tree, your program should print the tree level by level. Assume that the integer values are different. Your program should print the B - tree as follows ( The first number represents the value, the second number shows the parent node. L represents the left child, M represents the middle child, and R represents the right child )

input:
