First letter Capital of every word in a expression

Hi Experts,

I am trying to do a check using the match_regex to check in a expression if the first letter of every word are in capital.

If it find all staring letter in capital for every word in an expression then only it should return 1 else 0

Can anybody guide me on this.

Example : I Will Go Home - should return 1

                  I will go home   - should return 0
