C# Program to Reverse Each Word of a String

C# Program to Reverse Each Word of a String

Most of the IT companies check the coding skills and problem-solving skills as well along with the theoretical interview questions. Sometimes you are free to write the pseudo code and sometimes you are asked to write the complete program either on any paper or any editor. 

This question is asked in the coding interview to write the program. Here you can find the program as well as a live running program so that you can test the program immediately.

	StringBuilder reversedWord = new StringBuilder();  
	List<char> charList = new List<char>();  

	 for (int i = 0; i < inputString.Length; i++)

		 if (inputString[i] == ' ' || i == inputString.Length - 1)  
		 {  
			 if (i == inputString.Length - 1)  
				 charList.Add(inputString[i]);  
			 
			 for (int j = charList.Count - 1; j >= 0; j--)  
				 reversedWord.Append(charList[j]);  

			 reversedWord.Append(' ');  
			 charList = new List<char>();  
		 }  
		 else  
			 charList.Add(inputString[i]);

	return reversedWord.ToString();		
}
}

Output:
