How are postfix and prefix similar

WebThese changes to the position of the operator with respect to the operands create two new expression formats, prefix and postfix . Prefix expression notation requires that all operators precede the two operands that they work on. Postfix, on the other hand, requires that its operators come after the corresponding operands. WebA postfix expression is written exactly in computation order: e 0 e 1 o 1 ... ( e k o k)... e N o N Computation is r [ 1] = o 1 ( e 0, e 1) ... r k = o k ( r [ k − 1], e k) ... r N = o N ( r [ N − 1], e N) Infix is subjectively thought by many to be easier for humans to read and write.
