One, the development environment constructs At present, most developers in China are using winxp/win7/windows xx to do MCU development. Accustomed to the development of Windows environment friends, if once a contact to the MCU need to be a Linux environment for the development of compiling, the first response is, of necessity, "concubine can not do." For example, our protagonist ESP8266 this chip, the original supply is based on Linux development (the

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
