The idea is to use thestack data structureto convert an infix expression to a postfix expression. The stack is used to reverse the order of operators in postfix expression. The stack is also used to hold operators since an operator can’t be added to a postfix expression until both of its...
In the file dejkstra.c, Dijkstra's algorithm is implemented in the function: char *infix_to_postfix(char const *const infix); This function takes a string in infix form and returns a string in postfix form, where all elements (operands and operators) are separated by spaces, or NULL in...

Infix to Postfix Converter This JavaScript program converts infix expressions to postfix notation. It utilizes a stack-based approach to handle operators and parentheses. Approach Input: The user provides an infix expression (e.g., 3 + 4 * (2 - 1)). Tokenization: The input expression is spl...

To convert infix expression to postfix expression, we will use thestack data structure. By scanning the infix expression from left to right, when we will get any operand, simply add them to the postfix form, and for the operator and parenthesis, add them in the stack maintaining the precedenc...
