  • Example: 1 -> 2 -> 3 -> 4 -> 5 -> 2 (loop back to 2), the two pointers will meet at node 2.

A Software Developer was asked
Q. How can you check for integer overflow when multiplying two integers and ensure the result is stored correctly within an integer type?
Ans. 

To check for integer overflow when multiplying two integers, use the properties of integer overflow and check if the result is within the valid range of the integer type.

  • Check if the signs of the two integers are the same to avoid overflow in case of multiplication.

  • Use the properties of integer overflow to detect if the result exceeds the maximum or minimum value of the integer type.

  • Consider using a larger data ty...

  • Q2. What is the internal working mechanism of a HashMap?
  • Ans.
