Hi I need help please I need to make a function that converts an infix expression to a post fix expression such as converting a + b * (c-d) To a b c d - * +
Repeat the following for each element in an infix expression: ● If an operand is reached, append it to the postfix expression. ● ● ● If an open parentheses is reached, push it to the stack. If a close parenthesis is reached, pop the operators in the stack and append them to the postfix expression until an open parenthesis is popped. If an operator is reached, pop the operators in the stack that are of higher or equal precedence than the new operator and append them to the postfix expression. After that, push the new operator to the stack. When the end of the infix expression is reached, pop and append the remaining operators in the stack and append them to the postfix expression. ch this video and work
