With this transformation, we know that we only need the last two lengths when computing the current length values, therefore we can save memory by keeping only the last two rows. Method 1 (Brute Force) We can consider all sub-strings one by one and check for each sub-string both conditions together 1. sub-stringโ€™s distinct characters is equal to maximum distinct characters I created almost all solutions in 4 programming languages - Scala, Javascript, Java and Ruby. If we use brute-force and check whether for every start and end position a substring is a palindrome we have O(n^2) start - end pairs and O(n) palindromic checks. Get parts from existing strings with Substring. Solution. The algorithm processes all edges 2 more times. If the antivirus solution is too difficult to run, the user may disable it in the โ€ฆ We need to simplify our solution. Solution: We define lps2(i, len) = lps(i, i + len - 1).
