Empty space at strings[0][0]
Try to console.log function's input arguments and you'll see that the first string in strings has an empty space in the beginning. I was thinking that i'm mistaken somewhere but constraints say that the string consists of lowercase English letters

Case 1: console.log(strings)
[
' abc', 'bcd',
'acef', 'xyz',
'az', 'ba',
'a', 'z'
]

Case 2: console.log(strings)
[ ' a' ]
