Hi, What about adding a second map with a counter as a key, and the key as the value. So there are two maps:
map 1: key: counter; value: your key map 2: key: your key; value: your value plus the counter from map 1 Regards, Thomas On Sun, Apr 22, 2018 at 8:46 PM, ivan <[email protected]> wrote: > oh? that great! do you have any sample?
