Test Instructions: An alphabetic sequence of length m, consisting of n letters, each with two costs: ① delete the letter; ② Add the letter. Ask the minimum cost of turning this sequence into a palindrome sequence. the f[I [j] represents the minimum cost of I-J this section into a palindrome string. when sequence s[i] = = s[J], no cost is required: f[I [j] = f[i + 1][j-1];otherwise:①-> plus or minus the I-letter, f[i + 1 [j] + w[s[I]];②-> plus or minus the J-letter, f[I [j-1] + w[s[j]];(because a

Test instructions: Give you a M-bit string, where the character is one of the given n lowercase letters, and then the cost of adding or removing the letter in the stringNot the same. It is the minimum cost of the string to be a palindrome after adding a delete operation.Idea: Consider D[i][j] as the minimum cost of a palindrome string I to J.such as xx.....yy, if x = = Y, obviously d[i][j] = d[i+1][j-1];if x! = Y, then there are 4 scenarios: Delete x, add an x after Y, delete y, and add y before

Ask at least how much value, can make a string into a palindrome.IdeasIn fact the value of deleting or adding characters only needs to keep the smaller one. Assuming that you are currently converting (j,i) to a literal, it has the following three scenarios:(1) Add or remove at the end of a character that is the same as the beginning, f[j][i-1]+cost[s[i]-' a ';(2) Adding or deleting a character at

If we delete the "a" on the beginning-get "BCB", the cost would is 1100. If we insert "BCB" at the begining of the string, the cost would are + + + + =, which is the minimum.SourceUsaco Open GoldA look at this problem is always felt to be a string processing problems, in fact, it is necessary to model dynamic programming method.Dynamic programming meth
