Add the work done in a day

If a worker takes x days, one day’s work is 1/x of the job. Add these for workers on the same job.

Days together = xy ÷ (x + y) for two workers.

A takes 10 days, B takes 15. How many days together?Show the answerHide the answer

In a day: 1/10 + 1/15 = 1/6 of the job. So they take 6 days.

Longest substring without repeating charactersPython

    left = 0
    longest = 0
    for right, ch in enumerate(s):
        if ch in last:
            left = last[ch] + 1

RunInput “abba”Returned 3, expected 2

StudentMy code returns 3 for “abba” but the answer is 2. Why?

AceWhen right reaches the last “a”, where is left? Is the “a” you saw before still inside your window?
