| Hi guys,
|
| I need your assistance by the following problem:
|
| list1 = {{0,A,A,A}, {1,B,B,B}, {0,C,C,C},
{1,D,D,D}, {1,F,F,F},
| {0,G,G,G}, {0,H,H,H}}
|
| Every 1st element of the each sublist should be
checked. Is the first
| element a ZERO, this sublist should be removed
from the list. If it is
| a ONE - this sublist remains in the list.
|
| In this example the output should be:
|
| {{1,B,B,B}, {1,D,D,D},{1,F,F,F}}
|
| Thanks for your help!
