Hi all,
I have a 2D array as follow:
arr=[
[ 'a',1,2,3],
['b',4,5,6],
['c',3,2,1],
['a',1.3,2.2,3,3],
...
['a', 2,1,3],
...
['a',2.1,1.5,3]
]
As you can see there are several rows containing element 'a',
and the last row containing 'a'' is the lastest one. I wonder if it
is possible to return a new array which contains the latest row having
'a' ,
together with other rows.
Thanks,
Li
