Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

    • Traverse the tree level by level and keep track of the rightmost node at each level

    • Print the rightmost node of each level to get the right view of the tree

  • Ans. 

    Yes, the 0/1 Knapsack problem can be solved using dynamic programming with a space complexity of not more than O(W).

    • Use a 1D array to store the maximum value that can be stolen for each weight from 0 to W.

    • Iterate through each item and update the array based on whether including the item would increase the total value.

    • The final value in the array at index W will be the maximum value that can be stolen.

    • Calculate the total size of the array by multiplying the number of elements by the size of each element.

    • Divide the total size by the size of one element to get the size of the array.

    B+ trees are used for indexing in databases to efficiently search and retrieve data.

    • B+ trees are balanced trees where each node can have multiple keys and child pointers.

    • Data is stored in leaf nodes, while non-leaf nodes are used for navigation.

    • B+ trees are commonly used in databases because of their ability to efficiently search and retrieve data.
