Breadth-First Search (BFS) Approach

  1. Initialize a queue and add the start value to it.
  2. Initialize a visited set or array to keep track of visited values.
  3. Initialize an operation counter ops to 0.
  4. While the queue is not empty: a. Increment ops. b. For each element in the queue: i. Remove the element from the queue. ii. If the element is equal to goal, return ops. iii. If the element is out of the range [0, 1000], skip further processing. iv. If the element has not been visited: - Mark it as visited. - Perform each operation (addition, subtraction, XOR) with all numbers in nums and add the results to the queue if they haven't been visited.
  5. If the goal is not reached and the queue is empty, return -1.
