To find a loop in a linked list, we use Floyd's cycle-finding algorithm.
Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.
If there is a loop in the linked list, the two pointers will eventually meet.
To detect the meeting point, we reset one of the pointers to the head of the linked list and move both pointers at the same speed.
The meeting point is the start of the loop.

Handling if statements in macros requires careful consideration of syntax and logic.
Use proper syntax and indentation to ensure the if statement is clear and readable.
Consider using nested if statements or logical operators to handle multiple conditions.
Test the macro with different input values to ensure the if statement behaves as expected.
XOR of 0xFE and 0xEF is 0x11.
XOR operation compares bits of two numbers and returns 1 if they are different, 0 if they are the same.
0xFE in binary is 11111110, 0xEF in binary is 11101111.
Performing XOR operation on 0xFE and 0xEF results in 00010001, which is 0x11 in hexadecimal.
One line codes that can cause runtime exceptions
Dividing by zero: int result = 5 / 0;
Accessing index out of bounds: int[] arr = new int[3]; int value = arr[3];
Null pointer exception: String str = null; int length = str.length();
Hex representation of -17 is FFFFFFFF
Convert the decimal number -17 to binary: 17 = 0001 0001
Take the two's complement of the binary number: 1110 1111
Convert the two's complement binary number to hex: FFFF
The number of nodes with NULL children in a binary tree with N nodes is N-1.
In a binary tree, each node can have at most 2 children.
The number of NULL children for each node is either 0, 1, or 2.
The total number of NULL children in a binary tree with N nodes is N-1.
