This is leetcode problem 2053
In an array of strings, we're on a quest
For those that stand alone, unique from the rest
Distinct strings are our treasure, appearing just once
We'll count them carefully, no need to be a dunce
K-th distinct, that's what we seek
In order they appear, no need to tweak
If K's too big, an empty string we'll find
But if it's just right, the answer we'll unwind
We start by counting, each string we tally
How many times they show, we'll keep a rally
A hash map's our tool, to track every word
Counting occurrences, leaving none unheard
Now we loop through, checking one by one
Is it unique? Our search has begun
We count distincts, until we reach K
If we find it, that's the string we'll play
K-th distinct, that's what we seek
In order they appear, no need to tweak
If K's too big, an empty string we'll find
But if it's just right, the answer we'll unwind
If our count falls short, and K's out of reach
An empty string's returned, that's what we'll teach
But if we succeed, the K-th distinct we'll show
That's our solution, now you're in the know
