Swap Two Characters in a Java String One of the string value’s main properties is that it is immutable, meaning it cannot be changed. To perform the swap operation, we first have to copy theStringobject to aStringBuilderor a character array. These two data types allow us to perform swap...
For swapping two strings from one location to another location, we use strcpy() function. An array of characters (or) collection of characters is called a string. Declaration Following is the declaration for an array − char stringname [size]; For example, char string[50]; string of ...
Swapping any two characters results in S remaining aaaaa. Thus, only one string can result from the operation. 组合数,先总数也就是n*(n-1)/2 ,因为有相同的就要减去相同的时候交换的次数。 但是最后还要判断same的数量最后res++, 错就错在这里了。 --- importjava.util.Scanner;publicclassAbc345{p...
Given a binary string s, return the minimum number of character swaps to make it alternating, or -1 if it is impossible.The string is called alternating if no two adjacent characters are equal. For example, the strings "010" and "1010" are alternating, while the string "0100" is not....
Given a stringtext, we are allowed to swap two of the characters in the string. Find the length of the longest substring with repeated characters. Example 1: Input: text="ababa" Output:3Explanation: We can swap thefirst'b'withthelast'a',orthelast'b'withthefirst'a'.Then, the longest ...
characters "a" and "b". Output If it is impossible to make these strings equal, print −1 . Otherwise, in the first line print k — the minimum number of operations required to make the strings equal. In each of the next k lines print two integers — the index in the string s ...

The third line contains one string tt consisting of nn characters "a" and "b". Output If it is impossible to make these strings equal, print −1−1. Otherwise, in the first line print kk — the minimum number of operations required to make the strings equal. In each of the next ...
