◆EXPRESSION
Using the 10 digits (0,1,2,3,4,5,6,7,8,9), four arithmetic operations
("+","-", "x", " /"), exponentiation ("^"), factorial ("!"), decimal point
("."), and one pair of parentheses exactly one time, form an expression with
maximum possible result.
Example:
(2.3/1-0+4x65)^789!
Notes:
- Order of operations: 1.(Factorial), 2.(Exponent), 3.(Multiplication and
Division), 4.(Addition and Subtraction). Expressions inside the parentheses
should be evaluated first.
- The signs "+", and "-" can be used only for addition and subtraction
operations (not for assigning positive or negative values to the numbers).
- The decimal point should be between two digits.
- Operations having undefined results (like division to zero) are not allowed.
使用所有數字 (0,1,2,3,4,5,6,7,8,9)、四則運算 (加 "+", 減 "-", 乘 "x", 除 "/")
、指數 ("^")、階乘 ("!")、小數點 (".")、以及一對小括號各恰好一次,
做出一個結果最大的式子。
例子:
(2.3/1-0+4x65)^789!
注意:
* 計算順序為: 1. 階乘, 2. 指數, 3. 乘除, 4. 加減。括號內的式子先算。
* "+" 和 "-" 僅可用來表示加和減,不可表示正數或負數。
* 小數點必須在兩個數字之間。
* 不允許式子有未定義的結果 (例如除以零等)。
