Hello
If you want to remove all occurences of x in y, it's simple in J:
y-.x
For example,
1 2 3 1 9 10 8 1 -. 1
2 3 9 10 8
Now, if you want to remove n occurences of x in y, how would you do that?
Following is my quick and dirty solution:
removen=.13 : 'y#~-.((x>:]) *. 0&~:) (*+/\) (={.)y'
3 removen 'fasdffgh flkjffif'
asdgh flkjffif
3 removen 1 1 2 3 1 9 10 8 1
2 3 9 10 8 1
I used the first item in y as the "item to remove" -- smiliar to the cut
verb.
I believe there are simpler solutions as always(you may relax the constrain
for keeping the order of y). Any suggestions?
