Leetcode Problem 1863. Sum of All Subset XOR Totals

1863. Sum of All Subset XOR Totals

Leetcode Solutions

Backtracking to Generate Subsets and Calculate XOR

  1. Define a helper function that takes the current index, the current XOR value, and the running total sum.
  2. If the current index is equal to the length of the input array, add the current XOR value to the total sum.
  3. Recursively call the helper function twice: once including the current element in the XOR calculation, and once excluding it.
  4. The base case is reached when the current index is equal to the length of the input array.
  5. Return the total sum after all recursive calls have completed.
