Compare two strings A and B, determine whether A contains all of the characters in B. The characters in string A and B are all Upper Case letters. Example For A = "ABCD", B = "ABC", return true. For A = "ABCD" B = "AABC", return false. 1. 2. 3. 4. 5. 6. 7. 8. ...
#Case-insensitive string comparison in Python In our above examples, we use the case of letters for string comparison. However, if you want the string comparison to be case-insensitive, use the lower() method with the strings you are comparing. Here is an example. string1="hello"string2="...
