本文介绍了一个程序，用于将输入的句子旋转90度，从左到右显示变为从上到下，从右到左。适用于文本处理和编程爱好者。

Rotating Sentences

In ``Rotating Sentences,'' you are asked to rotate a series of input sentences 90 degrees clockwise.So instead of displaying the input sentences from left to right and top to bottom, your programwill display them from top to bottom and right to left.

Input and Output

As input to your program, you will be given a maximum of 100 sentences, each not exceeding100 characters long. Legal characters include: newline, space, any punctuation characters, digits,and lower case or upper case English letters. (NOTE: Tabs are not legal characters.)

The output of the program should have the last sentence printed out vertically in the leftmostcolumn; the first sentence of the input would subsequently end up at the rightmost column.

Sample Input

Rene Decartes once said,
"I think, therefore I am."

Sample Output

"R
Ie
 n
te
h 
iD
ne
kc
,a
 r
tt
he
es
r
eo
fn
oc
re
e
 s
Ia
 i
ad
m,
.
"

#include <stdio.h>
#include <string.h>

int main(void)
{
    char str[111][111];
    int max=0,len[111];
    int i,j,k=0;
    
    while(gets(str[k]) != NULL)
    	k++;
    
    for(i=0;i<k;i++)
    {
    	len[i] = strlen(str[i]);
    	if(max<len[i]) max=len[i];
    }
    for(i=0;i<max;i++)
    {
    	for(j=k-1;j>=0;j--)
        {
            if(i<len[j])
                printf("%c",str[j][i]);
            else
                printf(" ");
        }
        printf("\n");
    }

    return 0;
