Una versión simplista de la calculadora numérica inglesa

Tarea

Escriba un programa que tome una cadena como entrada y genere el resultado de la expresión.

Reglas

La cadena de entrada estará redactada y no será numérica.

No habrá paréntesis.

El orden de cálculo será dividir, multiplicar, restar y luego sumar.

Para las mismas operaciones, los cálculos deben hacerse de izquierda a derecha.

Todos los números de entrada serán enteros de -999 a 999 (ambos incluidos)

La salida será un número entero de cualquier rango.

La división siempre será perfectamente divisible y cero nunca será un denominador.

La restricción de mayúsculas y minúsculas para la entrada es opcional. No tiene que verificar la validez de la entrada.

Formato numérico

0 to 20 -> zero,one,two...nineteen,twenty
21 to 99 -> twenty one,twenty two.....ninety eight,ninety nine
100 to 999 -> one hundred, one hundred one, one hundred two...one hundred ten....two hundred fifty....nine hundred ninety eight,nine hundred ninety nine

Para números negativos: agregue minusa su equivalente positivo

Formato de operación

Addition: one plus two
Subtraction: one minus two
Multiplication: one time two #Note that for one on the left of multiplication, it is one time and not times.
                two times one hundred
Division: forty divided by two

Ejemplos:

o/p <- input

20     four times five
35     twenty plus fifteen
70     fifty plus five times four
-90    minus one time ninety
25     twenty one minus minus four
45     ninety divided by two
700    one time seven hundred 
555    one hundred eleven times two plus three hundred thirty three
99     one hundred plus minus one
45     forty five plus two hundred times zero
 4     four
-3     three minus three minus three

Ejemplo paso a paso:

• Entrada: two hundred twenty two divided by two times minus fifty seven plus three hundred eighteen minus minus ten
• Paso 1: Eliminar "por": two hundred twenty two divided two times minus fifty seven plus three hundred eighteen minus minus ten
• Paso 2: Convierta "cero" a "doce" con el número correcto: 2 hundred twenty 2 divided 2 times minus fifty 7 plus 3 hundred 8een minus minus 10
• Paso 3: eliminar todas las "t": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8een minus minus 10
• Paso 4: Reemplace todos los "een" con "+10": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8+10 minus minus 10
• Paso 5: Reemplace todos los "cien" con "* 100": 2 *100 weny 2 divided 2 imes minus fify 7 plus 3 *100 8+10 minus minus 10
• Paso 6: Reemplace todos ["wen", "hir", "for", "fif"] con el dígito correcto: 2 *100 2y 2 divided 2 imes minus 5y 7 plus 3 *100 8+10 minus minus 10
• Paso 7: Reemplace todas las "y" con "* 10": 2 *100 2 *10 2 divided 2 imes minus 5 *10 7 plus 3 *100 8+10 minus minus 10
• Paso 8: dividir entre ["más", "menos", "ime", "imes", "dividido"]: ["2 *100 2 *10 2 "," 2 "," "," 5 *10 7 "," 3 *100 8+10 "," "," 10"]
• Paso 9: Divida cada uno en espacios: [["2","","*100","2","*10","2",""],["","","2",""],["",""],["","5","*10","7",""],["","3","","*100","8+10",""],["",""],["","10"]]
• Paso 10: eliminar elementos vacíos: [["2","*100","2","*10","2"],["2"],[],["5","*10","7"],["3","*100","8+10"],[],["10"]]
• Paso 11: dividir en partes de tamaño 2 y unir: [["2*100","2*10","2"],["2"],"",["5*10","7"],["3*100","8+10"],"",["10"]]
• Paso 12: Python evalcada uno:[[200,20,2],[2],"",[50,7],[300,18],"",[10]]
• Paso 13: Suma cada uno: [222,2,"",57,318,"",10]
• Paso 14: vuelva a empujar la cadena del registro y elimine todo excepto las letras dividedimesminusplusminusminus
• Paso 15: Reemplace "más", "menos", "imes", "ime", "dividido" con los caracteres del operador y añádalos con un espacio: [" /"," *"," -"," +"," -"," -"]
• Paso 16: entrelaza y une ambos: 222 /2 * -57 +318 - -10
• Salida: Python evalla cadena, y salida implícitamente:-5999.0
