My brother asked me to reverse words in a sentence. He accused me of cheating by not writing an actual algorithm, but here is the solution I came up in a minute.

' '.join(s.split()[::-1])

C#

    public static string Reverse(string s)
    {
        char [] sbArray = s.ToCharArray();
        int len = s.Length;
        int middle = len/2;

        for (int i = 0; i < middle; i ++)
        {
            char ch = sbArray[i];
            sbArray[i] = sbArray[(len - 1) - i];
            sbArray[(len - 1) -i] = ch;

        }
        return new string(sbArray);
    }

Still C#, but using string builder

    public static string Reverse(string s)
    {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < s.Length ; i ++)
        {
            sb.Append(s[s.Length - 1 - i]);
        }
        return sb.ToString();
    }

Python

    def Reverse(s):
        return s[::-1]

I have been using Git a lot lately across different machines. Everytime I branch I create a tracking branch. Here is the command I use.

git branch —track version20 origin/version20

This mean local version20 will track remote version20
