1031 Hello World for U (20 branch )

The question

Give a string length n（5<=n<=80), Press this string U Glyph output .
The output is divided into three parts , The first part is long n1,U The left side of the , The second part is long n2,U The bottom of , The third part n3,U The right part of .
n1=n3<=n2, And n1 And n2 The difference should be as small as possible .n1+n2+n3-2=n.

Ideas

Handle the position of each character . front （n1-1） Line output U On both sides of , The number of spaces in the middle is n2, Change the space in the middle of the last line to the letter at the bottom of the output . Notice that the last letter of the first and third parts is at the bottom .

Code

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

char str[300];

void print1(int n2)
{
	for(int i=0;i<n2;i++){
		printf(" ");
	}
}

void print(int n1,int n2,int sum)
{
	for(int i=0;i<n1;i++){
		if(i!=0){
			printf("\n");
		}
		printf("%c",str[i]);
		if(i<n1-1){
			print1(n2);
		}else{
			for(int j=0;j<n2;j++){
				printf("%c",str[n1+j]);
			}
		}
		printf("%c",str[sum-1-i]);
	}
}
int main()
{
	
	int sum, n1, n2;
	scanf("%s",str);
	sum=strlen(str);
	n1=(sum+2)/3;
	n2=sum-n1*2;
	print(n1,n2,sum);
	return 0;
