9.2. Reversing Text¶
Run this next one, and look at how a simple change to the pattern gives a very different result. Here we’ll combine before rather than afterward, changing only Step 4 (how values are accumulated).
- Because we add each new letter at the end of
newStringB. - Each new letter gets added at the end, which creates a reversal.
- Because
newStringAis adding the characters from left to right. - How would that reverse the other string?
- Because we called a reverse function.
- There is no reverse function in this program.
- Because the
forloop is doing a reversal - The same
forloop is creating both an in-order copy of the string and a reversed order of the string. Theforloop is the same in both cases.
Why do you think newStringB has all the letters, but in the reverse order?
Write the code to make a palindrome with the string “popsicle”. Palindromes read the same foward and backwards. Example: appleelppa
