Web12 apr. 2024 · Vol. 149/4/1,442. After more than a decade of development delays, the littoral combat ship (LCS) is showing some usefulness in the fleet. But despite this progress, it remains a troubled program. The program is a favorite punching bag when it comes to examples of waste and failure. WebWe can memoize the function call using the functools.cache decorator. This will make the function run in O(n^2) time and O(n^2) space. For longest palindromic subsequence, we can just call the lcs function with the string and its reverse as the first two arguments, and the length of the string minus 1 as the last two arguments.
