Write a Java program to generate all possible permutations with repetition for a given string and limit the output to unique values. Write a Java program to recursively generate and print all permutations with repetition for a string of digits. Write a Java program to generate all repeated-charac...
We can use thereplaceAllmethod to replace all of the occurrences of a string with another string. The important point to note is thatreplaceAll()acceptsStringas argument, so you can use theCharacterclass to create a string and use it to replace all the characters with an empty string. privat...

Given a collection of numbers that might contain duplicates, return all possible unique permutations. 如果输入有重复怎么办。 我们可以利用Set, 可以在输出结果的时候比较是否有重复的结果。 我们也可以在每次swap的时候比较nums[i], nums[j]是否相同。

35. String Permutations with Repetition Write a Java program to print all permutations of a given string with repetition. Sample Output: The given string is: PQR The permuted strings are: PPP PPQ PPR ... RRP RRQ RRR Click me to see the solution ...
For the second part, it is tempting to start enumerating all possible permutations of the string, and passing each in turn to the above method. If the candidate suggests this approach, ask them about performance, both in Big-O terms and in practical terms. How long would you expect it to...
