For the given expression ,the required infix expression is ((1-4)^2)/((5-3)/2)+(9%4) =10 from the following algo:-

1.The reversed input string is completely pushed into a stack. prefixToInfix(stack) 2.IF stack is not empty a. Temp -->pop the stack b. IF temp is a operator Write a opening parenthesis to output prefixToInfix(stack) Write temp to output prefixToInfix(stack) Write a closing parenthesis to output c. ELSE IF temp is a space -->prefixToInfix(stack) d. ELSE Write temp to output IF stack.top NOT EQUAL to space -->prefixToInfix(stack)
so , the answer to it is 10
