Here are the seven strings: abc, ab, ac, bc, a, b, c. The one your algorithm overlooks is ac. When all the letters are the same, those seven strings are obviously all palindromes, so the result from count_palindromic_slices("aaa") should be 7. –
WebNov 11, 2024 · The algorithm for even-length palindromes has small modifications over the one for odd-length palindromes. Take a look at its implementation: This algorithm is similar to algorithm 2. However, we change the initial values of and to fit with the next range to check. The reason is that even-length palindromes have two center indexes.
