Java programming expression code example

Reverse Polish notation

Definition: the traditional four operations are called infix expressions, that is, the operator is between two operands. An inverse Polish expression is called a suffix expression, which is after the real operand.

Inverse Polish expression:

a+b ---> a,b,+ a+(b-c) ---> a,c,-,+ a+(b-c)*d ---> a,d,*,+ a+d*(b-c)--->a,+ a=1+3 ---> a=1,3 +
