sir Good Day :<br><br>PLT Schemes<br>i used this utility functions i used it to manipulate the stream such as map and filter.<br><br>> ( define (inc x) (+ 1 x))<br>>(define int (make-stream 0 inc )<br>>(define sqr x ))<br>> (stream-print (stream-map int sqr) 10)<br> ( 0 1 4 9 16 25 36 49 64 81 ) ...... output<br>>( stream-print (stream-filter int odd?) 15 )<br>( 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29)<br><br>i have to used the utility functions below <br><br>1. (stream-map stream op)<br>2.(stream-filter stream ok? )<br><br>" i used the accessor stream-current and stream-next to access the succeeding stream.<br><br><br>Thanks a lot i hope you give us ideas on this :)<br><br>More Power ...... <br><p>
