Write down the IJVM program which accepts RPN expression, with each operand and operator entered line by line. As each number (operand) is entered, push it on stack. As soon as operator (+, -, *, /) is entered, program should pop off top two values stack, apply operator on these values and push result on stack. Repeat this procedure for each operand/operator entered until user enters the "=" character which must display final result of expression from stack.
