i have to generate random numbers from length 2 to 30 and length two should have the numbers 1,2 and length 3 should have the numbers 1,2,3 so on and so forth till size 30.i should get an sequence like 2222221 or 1111112 till both the values appear and for 3 it should be 1222223 or 3331112.i should get similar output for all sizes which means i should get 30 sequences.but am getting only one
