"The main topic"Gives a string that can delete or add some characters, each of which consumes value. 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

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

Poj 3280 Cheapest Palindrome (DP) Question: There is a string consisting of n lower-case letters with a length of m. You can add or delete characters to it to convert it into a return text. Adding or deleting a character has a minimum cost. Idea: DP. Dp [I] [j] indicates the str [I ~ J] The minimum cost for returning objects. Therefore, the state transition equation is: When str [I] = str [j] dp [I] [j] = dp [I + 1] [J-1];When str [I]! = Str [j] dp
