Permutations of a String - Iterative Solution | String and Stringbuilders in JAVA

NADOS also enables doubt support, career opportunities and contests besides free of charge content for learning. In this video, we discuss the Permutations of a String problem with an iterative solution using the concepts of strings and stringbuilder. In this problem,

1. You are given a string.
2. You have to print all permutations of the given string iteratively.

The logic was out of the world. Thank you !!

[nidhipal]

The solution was out of the mind but after seeing the video CLICKED..
Thank you for your efforts sir !!!!

[rohandevaki]

this logic is very complex in the beginning itself

[harshitkaushik]

sir i m eager to start your level 2 intermediate. lots os love sir

[amanbhatt]

This approach is new and osm but only for distinct characters not for strings like aab, abba

[harishkunwar]

sir can we do same logic for integer values

[nitinchatwani]

will it work for string having similar letters like 'aab', 'abcb'? I think so it will fail at such test cases

[prateekbansal]

yeh trick sochi kese ?? kya koi or brute force method nahin hain isse iteratively solve krne ka ??

[as_wani]

If there are repeating characters in input string like "ABA", it will generate duplicates which someone from comments section has already pointed out. What I do is instead of printing the character to console, I append it to one more StringBuilder and after inner loop exits, I add that permutation to a set - New StringBuilder per outer loop iteration. Works but not sure if it is the efficient way to handle duplicates .

[sourabhyogi]

how did you came up with this approach??

[codebits]

Sir agar string ka length 12 se bda hua to factorial ke large value ki vajah se integer overflow ho jayega

[arex-gaming]

sir pepcoding site pe direct answer video hi show ho rha h string ke question me!

[prakharagarwal]

sir aisa ho kaise gya?? trick ko samjh mei ayi... matlab apki language mei bole to how samjh mei aya but why nhi?? =^D .and again.. thanks a lot sir...

[vishalit]

You are a mathematical scientist declared by your youtube student who will be become a great Scientists.

Sir which software you use for drawing.
It is good for us to visualize or draw problem and algorithms before coding
Please tell us the name of software🙏🏻🙏🏻

[dhruvtrehan]

Sir, agar yeh situation hoh pehle A waale permutation, fr B waale permutation, fr C waalw permutation in ABC toh fr kya krenge? Kaise hoga?

[indranilchakraborty]

Sir pepcoding t-shirt mei ak lena chata hon. Kaise milega...?

[harshit]

Sir what is the name of this algorithm? I didn't understand why this works ??

[rohitmeena]

Sir kitne dino me click kiya ye algo aapko?? 🙇‍♂️🙇‍♂️

[sainathreddy]

the next permutaion of abc should be acd not bac . it was printing all the permutationns but not in order
