How do you write algorithm to convert feet to meter?
To write an algorithm for converting feet to meters, you start by defining the conversion factor, which is 1 foot equals 0.3048 meters. Next, prompt the user to input a value in feet. Then, multiply the input value by the conversion factor (0.3048) to obtain the equivalent value in meters. Finally, display the result to the user.
How much is a pica in inches?
"Pica" is a prefix, not a base unit, so there isn't a conversion factor available for this. What kind of "expert" is this? (Pica is a type size. Pico is a prefix. You must have been educated in a government school.)
How many grams are in 0.054kg?
Prefix 'kilo' is used to denote multiples of gram and uses factor 1000. To convert kilograms to grams, value in kilograms has to be muliplied by conversion factor used with prefix 'kilo': 0.054 kilograms = 0.054 * 1000 = 54 grams

Program to convert a infix expression in to postfix and prefix expression in php?
To convert an infix expression to postfix and prefix in PHP, you can implement the Shunting Yard algorithm for postfix conversion and a modified approach for prefix conversion. For postfix, you use a stack to reorder operators based on their precedence and associativity while scanning the infix expression. For prefix, you can reverse the infix expression, convert it to postfix, and then reverse the resulting postfix expression. Here’s a brief code outline for both conversions: function infixToPostfix($infix) { // Implement the Shunting Yard algorithm to convert infix to postfix } function infixToPrefix($infix) { // Reverse the infix expression // Convert to postfix using infixToPostfix // Reverse the postfix result to get prefix } You would need to handle operators, parentheses, and precedence rules within these functions.
What is the time complexity of infix to post fix conversion algorithm?

Algorithm for infix to prefix conversion?
Algorithm to Convert Infix to Prefix FormSuppose A is an arithmetic expression written in infix form. The algorithm finds equivalent prefix expression B.Step 1. Push ")" onto STACK, and add "(" to end of the AStep 2. Scan A from right to left and repeat step 3 to 6 for each element of A until the STACK is emptyStep 3. If an operand is encountered add it to BStep 4. If a right parenthesis is encountered push it onto STACKStep 5. If an operator is encountered then:a. Repeatedly pop from STACK and add to B each operator (on the top of STACK) which has same or higher precedence than the operator.b. Add operator to STACKStep 6. If left parenthesis is encontered thena. Repeatedly pop from the STACK and add to B (each operator on top of stack until a left parenthesis is encounterd)b. Remove the left parenthesisStep 7. Exit
Program to convert infix to prefix?
I dont have the idea about the program but I know that prefix means the first starting letters of a particular things. I really think so there is a progam to convert infix to prefix but i might have misunderstood your question can you make it little simpler please.
