thanks for the reply
actually am supposed to generate random numbers in oncreasing size.
so when i say 1,2 i should get something like 12222 or 221 or 1112 ...i
should get both the values 1 and 2 in a random order but it should stop when
both the values occur atleast once in the sequence.so after 1,2 it should be
1,2,3 and the sequence generated should have 1,2,3 atleast once.then it
should generate a random sequence of numbers 1,2,3,4 ...it should go on till
it generates 1,2....30.hope am clear now.
