    # Pattern 1: B' < A' < C'
    # Possible operations: Y (B and C), Z (A and C)
    # To achieve B' < A' < C', we need to reduce B and C more than A
    # Let's try to find possible y and z such that B - x - y < A - x - z and A - x - z < C - y - z
    # Simplifying, y > B - A + z and y < C - A + x
    # This is complex, so we try possible minimal operations

    # Another approach: iterate over possible reductions and check conditions
    # This approach is not feasible for large numbers, but given the problem constraints, we can limit the trials

    # Check possible combinations of operations that can lead to valid Kadomatsu sequences
    # For each possible pattern, compute the required operations and check validity

    # Given the complexity, we'll try to find minimal x, y, z for each case

    # Case 1: B' < A' < C'
    # B - x - y < A - x - z => B - y < A - z => y > B - A + z
    # A - x - z < C - y - z => A - x < C - y => y < C - A + x

    # Given the complexity, we can try to find minimal z and compute x and y
    # However, this might not be feasible for large numbers, but given the problem constraints, we can limit the trials

    # Instead, we can use mathematical approach to find x, y, z that satisfy the conditions
    # Let's consider possible minimal reductions

    # Another approach: try all possible combinations of x, y, z up to a certain limit
    # Given the time constraints, we can try up to 2 steps for each variable (as the minimal solution might be small)

    # This approach is not optimal but can handle some cases

    # The range is arbitrary and might need adjustment based on problem constraints
