  • The search words are always indicated in the lowercase.
  • If the word wasn’t found even once, it has to be returned in the dictionary with 0 (zero) value.

Input: The text and the search words array.

Output: The dictionary where the search words are the keys and values are the number of times when those words are occurring in a given text.
