  • Q3. Favorite subject and basic questions from it
  • Q4. What is the angle between minute and hour hand for a particular time ?
  • Ans. 

    The angle between minute and hour hand for a particular time can be calculated using a formula.

    • The formula is: |(30*H) - (11/2)*M| degrees

    • Where H is the hour hand position and M is the minute hand position

    • If the result is greater than 180 degrees, subtract it from 360 degrees to get the acute angle

    • For example, at 3:15, H=3 and M=15, so the angle is |(30*3) - (11/2)*15| = 7.5 degrees

Do practice a lot of questions on linked list and stacks as these are two most important data structures asked in the interview. Also, try to implement it yourself without seeing the solution. Also prepare for Computer Science subjects like Operating System, Database Management System, Computer Networks, etc. I prepared them through Coding Ninjas notes which were simpler and easy to understand.

  • Ans. 

    Locate sum of 2 numbers in a linear array (unsorted and sorted) and their complexities

    • For unsorted array, use nested loops to compare each element with every other element until the sum is found

    • For sorted array, use two pointers approach starting from the beginning and end of the array and move them towards each other until the sum is found

    • Complexity for unsorted array is O(n^2) and for sorted array is O(n)
