Core ConceptsBefore defining a linear basis, it is essential to understand the following terms regarding bitwise XOR operations on integer sets:XOR SumFor a given set of unsigned integers Z, the XOR sum is the cumulative XOR of all its elements: Z1 ⊕ Z2 ⊕ ... ⊕ Zn.SpanThe span of a set Z, denoted as span(Z), represents the set ...

Balanced String Analysis (Simple and Extended) Problem Statement We need to analyze strings composed of 0, 1, and ?. The question marks can be replaced with either 0 or 1. The goal is to compute how many valid configurations result in "balanced" strings according to a specific criterion. Simple Approach For small lengths, a brute-forc ...

Construction AlgorithmThe Linear Basis structure maintains a set of linearly independent vectors to solve problems involving the XOR operation. To insert a value into the basis, we process the bits from the most significant bit (MSB) to the least significant bit (LSB).Let basis[] be the array storing the basis elements, initialized to 0. For an ...
