I approach dynamic objects by analyzing their behavior and adapting my approach accordingly.
I start by understanding the nature of the dynamic object and its expected behavior
I then analyze its movement patterns and any potential obstacles or hazards
Based on this analysis, I adapt my approach to ensure safe and efficient interaction with the dynamic object
For example, when working with a moving conveyor belt, I would e...
Implicit and explicit wait are two types of wait in Selenium used to synchronize the test execution with the application.
Implicit wait is used to set a default waiting time for the web elements to load before throwing an exception.
Explicit wait is used to wait for a specific condition to occur before proceeding with the test execution.
Implicit wait is set globally for the entire test script while explicit wait is set f...

Multi tasking, multi processing, and multi programming are different approaches to managing tasks in an operating system.
Multi tasking allows multiple tasks to run concurrently on a single processor.
Multi processing involves multiple processors running tasks simultaneously.
Multi programming allows multiple programs to be loaded into memory and executed concurrently.
Examples of multi tasking operating systems include Wi...
Use a shared variable and synchronization mechanisms to ensure natural order printing of numbers.
Create two threads, one for printing even numbers and the other for printing odd numbers.
Use a shared variable to keep track of the current number to be printed.
Implement synchronization mechanisms like locks or semaphores to ensure only one thread can access the shared variable at a time.
Each thread should check if it is i...

You are given a string 'STR'. Your task is to determine the total number of palindromic substrings present in 'STR'.
"abbc"
5
Count the total number of palindromic substrings in a given string.
Iterate through each character in the string and expand around it to find palindromic substrings.
Use dynamic programming to optimize the solution by storing previously calculated palindromic substrings.
Consider both odd and even length palindromes while counting.
Example: For input 'abbc', the palindromic substrings are ['a', 'b', 'b', 'c', 'bb'], totali...
