To check if a nonpal string can be made palindrome, just count the character counts, if length is even all the count should be devisable by 2 and if the length is odd one char is allowed can have count 1 and rest should be devisable by 2. example -> gffaa (not pal) but as g= 1, f =2 and a = 2 it can be made pal by shuffling "fagaf", I guess he was expecting this answer

after i saw this problem i tried this solution upto like for odd string and got suggestion on gpt to correct it hope it will help others to solve this one.
refer following code
public static boolean str) {
int oddcount = 0;
Map<Character, Long> collect = str.chars()
.mapToObj(c -> (char) c)
.collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));
for (Map.Entry<Character, Long> entry : collect.entrySet()) {
Character chars = entry.getKey();
Long count = entry.getValue();
//for odd character length
if (count % 2 != 0) {
oddcount++;
}
}
if (str.length() % 2 == 0) {
//if string length divisble by 2 then odd count should be 0 and return true else false
return oddcount == 0;
} else {
//if odd count is 1 then return true if not then return false here
return oddcount == 1;
}

}

code was simple itna mehnat hi kyun krna simply we can do it map mai dalke dekhlo if atmost 1 character is odd then it can be or else it can’t be palindrome, streams se easily ban jyega. I think interviewer was expecting this answer using streams

Interviewer asked about multithreading and he responded with microservices 😂

What was the answer to that csv question? How can we optimise that when saving the data in db?

I could see close to 100 videos of real interview experiences in your channel. All those interviews happened in the last month of notice? If yes, then how to manage work while giving these many interviews?

[omkarshendge]

Thanks for providing such helpful interviews though
