Infix to Postfix Expression
Infix to Postfix Expression Infix expression: The expression of the form a op b. When an operator is in-between every pair of operands. Postfix expression: The expression of the form a b op. When an operator is followed for every pair of operands. PROBLEM STATEMENT : Transform the algebraic expression with brackets into postfix form. Two-argument operators: +, -, *, /, ^ (priority from the lowest to the highest), brackets ( ). Operands: only letters: a,b,...,z. Assume that there is only one f=postfix form (no expressions like a*b*c). Input : t [the number of expressions <= 100] expression [length <= 400] [other expressions] Text grouped in [ ] does not appear in the input file. Output : The expressions in postfix form, one per line. Example Input: 3 (a+(b*c)) ((a+b)*(z+x)) ((a+t)*((b+(a+c))^(c+d))) Output: abc*+ ab+zx+* at+bac++cd+^* SOLUTION : Note : We can solve this problem using STACK.
