After reading the question, I have already typed it. You still need to understand it.   #include#include#includeusing namespace std;int c[50000],num[50000];int N=32100;int lowbit(int x){ return x&(-x);}int sum(int x){ int ret=0; while(x>0)

There is a random array of letters. Please write an algorithm with a time complexity of O (n) so that the installation letters are arranged in ascending order.Note: uppercase and lowercase letters are the same.Example: R, B, W, W, B, R, B, WAfter

In fact, it is very simple, but you can't remember it all the time, so write it alone! A. the pointer itself is immutable, that is, it cannot point to other objects: Char * const Pcontent = "ABCDE "; Pcontent [2] = 'F'; // valid Pcontent = "abfde"; /
