insert and delete the elements multiple times, so we cannot sort them every time, this method will inevitably time out. Here I use the STL et in STL (set cannot be used because there may be duplicate elements). set can be inserted and deleted in the time complexity of O (logn, in addition, the order will be maintained during the insertion and deletion process, so that we do not need additional sorting work, which undoubtedly saves time. However, set does not seem to allow random access. At leas

James found his friend Harry's love letter for his girlfriend. James is very fond of pranks, so he decided to hook up. He converted every word in the letter into a reply. For any given string, it can reduce the value of any character. For example, 'D' can be changed to 'C', which is an operation. (In addition, he can only reduce the character value to 'A', and 'A' cannot be reduced to 'Z '). Find the minimum number of operations required to convert a given string to a forward object. Input Forma
