## Description
|
||
|
|
<section id='description'>
|
||
|
|
La frase <a href="https://en.wikipedia.org/wiki/I before E except after C">"I antes de E, excepto después de C"</a> es una mnemotécnica muy conocida que se supone que ayuda cuando se deletrean palabras en inglés.
|
||
|
|
Usando las palabras proporcionadas, verifique si las dos sub-cláusulas de la frase son plausibles individualmente:
|
||
|
|
<ol><li style='margin-bottom: 5px;'> <i>"I antes de E cuando no está precedido por C".</i> </li><li> <i>"E antes que yo cuando está precedido por C".</i> </li></ol>
|
||
|
|
Si ambas subfrases son plausibles, entonces se puede decir que la frase original es plausible.
|
||
|
|
Escriba una función que acepte una palabra y verifique si la palabra sigue esta regla. La función debería devolver verdadero si sigue la regla de lo contrario falso.
