You are given an array $$$A$$$ of $$$N$$$ positive integers and you are allowed to construct new array $$$B$$$ in the following manner: Traverse $$$A$$$ from left to right and for each $$$i$$$ you can put $$$A_i$$$ either to the left or right of $$$B$$$ ($$$B$$$ is initially empty). You need to maximize the sum of all prefix XORs of $$$B$$$, that is, maximize $$$(B_1) + (B_1 xor B_2) + (B_1 xor B_2 xor B_3)...$$$

This question was asked in an online assessment for which one of my friends appeared. Both of us weren't able to solve it. Can someone please help me out?

Hello again everybody! How's it going?

I have developed a Chrome Extension that goes by the name CP Calendar , which helps you get the schedule of all Competitive Programming contests, hosted by various well-known platforms, listed in a single place. Sounds cool?

It's completely FREE and what are you waiting for? Do try it out from the Chrome Web Store, drop a rating / review if you find it helpful.

A share with your programming friends or your college community would be considered gold.

Platforms supported: -------------------- - Atcoder - CodeChef - Codeforces - GeeksForGeeks - Google - HackerEarth - Leetcode - TopCoder

ADD TO CHROME

Happy Coding!
