Hi, I want to separate my matrix according to certain value in the key assigned in containers.Map

1. One/1
2. Two/2
3. One/11
4. One/111

i want to make it into 2 matrix which are One [1 11 111] and Two[2] i was told that I can use strplit function, however I doesnt now how to using it in containers.Map.

Please guide. Thank you

Why do you get keys including numbers in the first place?
