I HOPE THIS WILL HELP U OUT...
ALGO GOES LIKE THIS: Reverrse prreffiix and evalluatte iitt
reverse given prefix expression;
scan the reversed prefix expression;
for each symbol in reversed prefix
if operand then
push its value onto stack S;
if operator then {
pop operand1;
pop operand2;
compute result = operand1 op operand2;
push result back onto stack S;
}
return value at top of stack;
AND EXAMPLE IS:Prefix: */-abc-+def Reversed: fed+-cba-/*
ch action stack
f push f
e push f e
d push f e d
+ pop op1 f e
pop op2 f
calc &push f (d+e)
- pop op1 f
pop op2
calc & push ((d+e)-f)
c push ((d+e)-f) c
b push ((d+e)-f) c b
a push ((d+e)-f) c b a
- pop op1 ((d+e)-f) c b
pop op2 ((d+e)-f) c
calc & push ((d+e)-f) c (a-b)
ch action stack
/ pop op1 ((d+e)-f) c
pop op2 ((d+e)-f)
calc & push ((d+e)-f) ((a-b)/c)
* pop op1 ((d+e)-f)
pop op2
calc & push ((a-b)/c)*((d+e)-f)

The prefix anthro- means "man" An example would be anthropology or anthropomorphic.
The question is probably "What is a prefix?". A prefix is the first part of a word that changes the word's meaning. For example, "uninterested" in this word "un" is the prefix and "un" means "not". Also, "indescribable", "in" is the prefix and "in" means "not" as well. One more: "inflammable", "in" is the prefix again. However, this "in" means "is" (inflammable = is flammable).
The common prefix for one hundredth is centi. For example, one hundredth of a metre is one centimetre. One hundredth of a gram is one centigram.
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.
Example: prefix: * 2 + 3 4 infix: 2 * (3+4) postfix: 2 3 4 + *
You can use the longest Prefix Match algorithm in C programming by looking up the longest standard Python package match and then converting that from Python into C or C++ to figure out how to create the equivalent.
No, "countenance" does not have a prefix in it. It is a standalone word that means a person's facial expression or approval.

Prefix min refers to an algorithm that calculates the minimum value of a given subarray in an array. It does so by precomputing prefix sums or prefix minimums to quickly determine the minimum value in any subarray. This can be useful in various programming problems and optimizations.
An example word with the prefix "corp" is "corporation."

An example of a prefix for 'spell' is 'mis' for misspell.
The prefix with means against. An example is withdraw.
The prefix is -in, as in "incapable."
An example would be, in the word pro-democracy, pro is a prefix.
