The ASCII code of T is 116.

O's ASCII code is 111

The ASCII code of is 32

B's ASCII code is 98

The ASCII code of E is 101.

The ASCII code of is 32

O's ASCII code is 111

The r ASCII code is 114.

【Question 2]Write a program to search for strings with the required format, and output the repeated strings andString.

21:{
 

 
22:If(! Hash1.add (s [I])// Do not add the same string
 

 
23:Hash2.add (s [I]);// Add the same string not added by hash1
 

 
24:
 

 
25:}
 

 
26:Hash1.removeall (hash2 );// Set the hash1-hash2 to get strings with different occurrences
 

 
27:System.Out. Println ("Different words :"+ Hash1 );
 

 
28:System.Out. Println ("The same words are :"+ Hash2 );
 

29:

31:}
 

Test:

Matched correctly
To be or not to be

Different words: [not, or]

the same words are: [to, be]
