java - Is PushbackInputStream an alternative for making InputStream consumable repeatedly? -


as understood, inputstream once consumed, cannot reused/ re-read back, not have content.

but, using pushbackinputstream, unread bytes read inputstream.

can use pushbackinputstream safely make inputstream consumable repeatedly?

yes, within pushback limit, , bufferedinputstream mark() , reset() features , adequate buffer, if have solution involves re-reading input, designing wrong. compiler can proceed left right along input file without ever backtracking: can you.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
