NSString *word1 = @"word1";
NSString *word2 = @"word2";

//output : word1 word2
NSInteger loc = word3.indexOf(word2);
NSLog(@"%d",loc);
//output : 6
NSString *word4 = @"word4";
NSString *word5 = @"word5";
NSLog(@"%@",word3.replace(word1,word4).replace(word2,word5));
//output : word4 word5
BOOL isEqual = word4.isEqualTo(word5);
NSLog(@"%d",isEqual);
