    Hi,

    I'm new to perl. I want to operate array in this way:
    a). remove one item in an array. For example, @array=(1,3,2,4), and want to
    remove the 2nd item '3'-- @array=(1,2,4);
    b). find the difference of two arrays. For example,
    @a1=(1,3,4);@a2=(1,2,4,5); want to get @a2_new=(all items in @a2, but not in
    @a1)=(2,5);

    Does any one know how to write the scripte?
    Thanks in advance, and happy new year!
    Liang
