"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.)
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
An algorithm for constructing the convex hull
In Sanskrit, 'prameya' is the word for algorithm.
O(nlogn)
An algorithm can not be written with the following infix expression without knowing what the expression is. Once this information is included a person will be able to know how to write the algorithm.
Prefix, suffix and infix
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
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.
(a + b) * c / ((x - y) * z)
An example of a prefix in the English language is pre, meaning before. An example of a suffix would be ing, meaning a verbal action. An example of an infix would be ful, meaning full of.
Example: prefix: * 2 + 3 4 infix: 2 * (3+4) postfix: 2 3 4 + *
Linear data structure is used to convert the logical address to physical address .Stack is used in this and the various conversion such as postfix,prefix and infix notation are come in this
infix: old Egyptians/Assirs some thousands year before prefix: Jan Łukasiewicz (Polish Notation) postfix: Burks, Warren, and Wright (Reverse Polish Notation)
The prefix in "punctual" is "pun-" and the suffix is "-ual". In "punctilious", the prefix is "pun-", the infix is "-ctil-", and the suffix is "-ious".
