tango interview questions

During the interview, I was asked to solve a problem where I had to rearrange an array so that all even numbers are placed at even indices and all odd numbers at odd indices. I discussed my understanding of the problem, clarified whether the array would have an equal number of even and odd elements, and then explained a two-pointer approach to efficiently solve it. I implemented a solution where I used one pointer to track even indices and another for odd indices, swapping mismatched values as needed. After writing and testing the code, I explained the time and space complexity.
