Given a string str, the task is to swap adjacent characters of this string in C.
Input: str = "geeks" Output: NA Not possible as the string length is odd Input: str = "geeks" Output: egek
- Check if the length of the string is even or odd.
- If the length is even, swapping cannot be done.
- If the length is odd, take each character of the string one by one and swap it with the adjacent character.
Below is the implementation of the above approach:
- Permutation of a string with maximum number of characters greater than its adjacent characters
- Rearrange the characters of the string such that no two adjacent characters are consecutive English alphabets
- String with k distinct characters and no same characters adjacent
- Swap characters in a String
- Rearrange characters in a string such that no two adjacent are same
- Swap all occurrences of two characters to get lexicographically smallest string
- Java program to swap first and last characters of words in a sentence
- Rearrange characters in a string such that no two adjacent are same using hashing
- Minimum replacements to make adjacent characters unequal in a ternary string
- Minimum replacements to make adjacent characters unequal in a ternary string | Set-2
- Program to toggle all characters in a string
- Program to check if first and the last characters of string are equal
- Python program to check if a string contains all unique characters
- Program to find the product of ASCII values of characters in a string
- Program to print characters present at prime indexes in a given string
