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: 1 2 3 4 5 6 7 8 9 -1 expected output: 4 2 (4 L) 6-8 (4 R) 1 (2 L) 3 (2 R) 5 (6-8 L) 7 (6-8 M) 9 (6-8 R)
