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

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

Yes and it can be done optimally using java 8, process the string using group by and get the hashmap for char and their count. Then apply the check for even or odd length and check the entryset if it contains all the values for keys as you highlighted.

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 checkIsPossiblePalindrome(String str) { int oddcount = 0; Map collect = str.chars() .mapToObj(c -> (char) c) .collect(Collectors.groupingBy(Function.identity(), Collectors.counting())); for (Map.Entry 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; } }

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?

For me, there was not much work so I was giving 2-3 interviews daily

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

umm bro just one thing i wanted to ask as i'm curious how are u uploading such interviews with your face exposed and with the channel name containing your name, so dont u get like any warning from these companies because most people upload with covering their face and stuff! Thanks for providing such helpful interviews though

@codeAtoZ 3 ай бұрын

There are lot of interviews like this and they don't have much time to see all videos that to 1st round... Nobody stays permanent in any organisation. One of the interviewer was knowing me so it doesn't create much impact to you are not saying anything bad and putting down their reputation in public.
