about algorithms
First interview questions: 1) You have array of subsequent non-repeating integers, one is substituted with zero, then array is mixed, describe algorithm to sort array and find missing integer, its complexity. 2) Describe algorithm to find longest palindrome in a string, in what case amount of iterations will be biggest and in what smallest.
Q: In the Python programming assessment, I encountered questions that assessed knowledge about the mutability of data structures like tuples, lists, and dictionaries. Additionally, there were Object-Oriented Programming (OOP) questions. The coding portion involved real-time challenges, including tasks such as checking for palindromes, removing elements from data structures, and performing 3x3 array operations, such as calculating row sums, diagonal values, and column sums—all without utilizing external packages like NumPy.
