Une version simpliste de la calculatrice numérique anglaise

Tâche

Écrivez un programme qui prend une chaîne en entrée et génère le résultat de l'expression.

Règles

La chaîne d'entrée sera libellée et non numérique.

Il n'y aura pas de parenthèses.

L'ordre de calcul sera diviser, multiplier, soustraire puis ajouter.

Pour les mêmes opérations, les calculs doivent être effectués de gauche à droite.

Tous les nombres entrés seront des entiers de -999 à 999 (les deux inclus)

La sortie sera un entier de n'importe quelle plage.

La division sera toujours parfaitement divisible et zéro ne sera jamais un dénominateur.

La restriction de cas pour l'entrée est facultative. Vous n'avez pas à vérifier la validité de l'entrée.

Format de nombre

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

Pour les nombres négatifs: ajouter minusà son équivalent positif

Format d'opération

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

Exemples:

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

Exemple étape par étape:

• Contribution: two hundred twenty two divided by two times minus fifty seven plus three hundred eighteen minus minus ten
• Étape 1: supprimer "par": two hundred twenty two divided two times minus fifty seven plus three hundred eighteen minus minus ten
• Étape 2: Convertissez "zéro" en "douze" avec le nombre correct: 2 hundred twenty 2 divided 2 times minus fifty 7 plus 3 hundred 8een minus minus 10
• Étape 3: supprimez tous les "t": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8een minus minus 10
• Étape 4: Remplacez tous les "een" par "+10": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8+10 minus minus 10
• Étape 5: remplacez tous les "centaines" par "* 100": 2 *100 weny 2 divided 2 imes minus fify 7 plus 3 *100 8+10 minus minus 10
• Étape 6: Remplacez tous ["wen", "hir", "for", "fif"] par le chiffre correct: 2 *100 2y 2 divided 2 imes minus 5y 7 plus 3 *100 8+10 minus minus 10
• Étape 7: Remplacez tous les "y" par "* 10": 2 *100 2 *10 2 divided 2 imes minus 5 *10 7 plus 3 *100 8+10 minus minus 10
• Étape 8: Diviser par ["plus", "moins", "ime", "imes", "divisé"]: ["2 *100 2 *10 2 "," 2 "," "," 5 *10 7 "," 3 *100 8+10 "," "," 10"]
• Étape 9: Divisez chacun des espaces: [["2","","*100","2","*10","2",""],["","","2",""],["",""],["","5","*10","7",""],["","3","","*100","8+10",""],["",""],["","10"]]
• Étape 10: supprimer les éléments vides: [["2","*100","2","*10","2"],["2"],[],["5","*10","7"],["3","*100","8+10"],[],["10"]]
• Étape 11: Divisez en parties de taille 2 et joignez: [["2*100","2*10","2"],["2"],"",["5*10","7"],["3*100","8+10"],"",["10"]]
• Étape 12: Python evalchacun:[[200,20,2],[2],"",[50,7],[300,18],"",[10]]
• Étape 13: Additionnez chacun: [222,2,"",57,318,"",10]
• Étape 14: Repoussez la chaîne du registre et supprimez tout sauf les lettres: dividedimesminusplusminusminus
• Étape 15: Remplacez "plus", "moins", "imes", "ime", "divisé" par les caractères de l'opérateur et ajoutez-les par un espace: [" /"," *"," -"," +"," -"," -"]
• Étape 16: entrelacer et joindre les deux ensemble: 222 /2 * -57 +318 - -10
• Sortie: Python evalla chaîne, et sortie implicitement:-5999.0
