Basic exercises--alphabet graphics

Problem Description

Using letters to make some beautiful graphics, here's an example:

ABCDEFG

Babcdef

Cbabcde

Dcbabcd

Edcbabc

This is a 5 row 7-column graph, find out the pattern of the graph, and output an n-row m-column graph.

Input Format

Enter a row that contains two integers n and m, representing the number of columns of the number of rows of the graph you want to output.

output Format

Output n lines, each m characters, for your graphics.

Sample Input

5 7

Sample output

ABCDEFG
Babcdef
Cbabcde
Dcbabcd
Edcbabc

data size and conventions

1 <= N, M <= 26.

The C + + code is as follows:

#include <iostream>
#include <cmath>
 
using namespace std;
 
int main ()
{
         intn;                  N is the row
         Intm;                 M is column
         cin>>n>>m;
         Chara= ' A ';        As output cardinality for
         (inti=0;i<n;i++)
         {for
                   (intj=0;j<m;j++)
                   {
                            cout<< char (A+abs (i-j ));
                   }
                  
                   cout<<endl;
         }
         Return0;
}
