Sample Run:
sentence = "Now is the time for the birthday party"
The length of sentence = 38
The character at index 16 in sentence = f
The index of first t in sentence = 7
The index of for in sentence = 16
sentence.substring(0, 6) = "Now is"
sentence.substring(7, 12) = "the t"
sentence.substring(7, 22) = "the time for th"
sentence.substring(4, 10) = "is the"
str1 = "Now is t"
str2 = "w is the t"
sentence in uppercase = "NOW IS THE TIME FOR THE BIRTHDAY PARTY"
str1 = "birthday party"
sentence.replace('t', 'T') = "Now is The Time for The birThday parTy"
