Hello World!
String length with rstrlen = 12
String length with strlen = 12
Testing rstrlen.
String length with rstrlen = 16
String length with strlen = 16
strlen is more
String length with rstrlen = 14
String length with strlen = 14
efficient than rstrlen.
String length with rstrlen = 23
String length with strlen = 23
