Or probably, my data set cal also be:

30 abcd
40 xycz
42 wxy

100 abc
20 abcd
30 abcc
99 abc

In this case: for abc, it should be
5 abc
1 abc

<<< Need to print 2 times for abc, as it occurs 4 times.

I'm sure there will be better solutions (which I'm eagerly awaiting from this great NG) but here's my stab at it.

{ if (a[$2]=="") {
a[$2] = $1
}
else {
a[$2] = a[$2] - $1
print $2, a[$2]
a[$2]=""}
