In this version of the task, the sizes of copied files do not exceed1000$\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">1000</span></span>}$byte.

You are copying from one server to another𝑛$n$files size𝑎1,𝑎2,…,𝑎𝑛$a_{\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">1</span></span>}}<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">,</span></span>{\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">a</span></span>}}_{\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">2</span></span>}}<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">,</span></span>\dots <span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">,</span></span>{\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">a</span></span>}}_{\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">n</span></span>}}$byte. The files are copied sequentially in the specified order.

When copying, you see two progress bars: the first shows the percentage of copied data in the current file, and the second shows the total percentage of copied data for all𝑛$\mathrm{<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;">n</span></span>}$files. Both percentages are displayed rounded down to a whole number. The values ​​on the progress bars are updated after each byte is copied.

Formally, after copying the byte number𝑥$x$from file number𝑖$i$first progress bar shows⌊100⋅𝑥𝑎𝑖⌋$<span\; style="transition:\; none\; 0s\; ease\; 0s;\; vertical-align:\; inherit;"><span\; style="transition:\;
