total [terminology]

Terminology¶

Usage¶

• Use for an additive numeric accumulator.
• It represents a running sum rather than a number of items.
• Prefer a domain-specific name such as profit when it communicates more.
• Do not use it for multiplicative accumulators, frequencies, or optimum tracking.

while l1 or l2 or carry:
    total = carry
    if l1:
        total += l1.val
        l1 = l1.next
    if l2:
        total += l2.val
        l2 = l2.next
    carry, digit = divmod(total, 10)
    tail.next = ListNode(digit)
    tail = tail.next
