Check if a String Is an Acronym of Words
We can implement the isAcronym
function to check whether the string s
is an acronym of the words in the array words
. We’ll do this by extracting the first character of each word and concatenating them to form a new string. Then, we’ll compare this new string with s
. If they are the same, s
is an acronym of words
; otherwise, it’s not.
Here’s the implementation:

Explanation
- Create the Acronym: We iterate through each word in
words
and take the first character, concatenating them to form a stringacronym
. - Compare with s: We check whether
acronym
is equal tos
. If it is,s
is the acronym ofwords
, and we returntrue
; otherwise, we returnfalse
.
The code has a time complexity of O(n)
, where n
is the total number of characters in the words
array. It follows the constraints provided and returns whether s
is an acronym of words
or not.
