You reach the last return statement when len>=2


You could also have written
if(len>=2){
newNums[0]=nums[0];
newNums[1]=nums[1];
return newNums;
}
else{
return nums;
}

i see the point and pass all tests as above.

Is it always good practice to have separate returns in if and else blocks and do not have return at the end of the method before closing the method?
please advise
