## Description
<section id='description'> 
Dado la matriz <code>arr</code> , iterar a través y eliminar cada elemento comenzando desde el primer elemento (el índice 0) hasta que la función <code>func</code> devuelva <code>true</code> cuando el elemento iterado se pasa a través de él. 
Luego, devuelva el resto de la matriz una vez que se cumpla la condición; de lo contrario, <code>arr</code> debe devolverse como una matriz vacía.
