정올 165 : 배열2-형성평가6

My Solution

#include<stdio.h>
int main(void){
    int arr[5][5]={{1,0,1,0,1},};
    int i,j;
    for(i=1;i<5;i++){
        for(j=0;j<5;j++){
            if(j==0){
                arr[i][j] = arr[i-1][j+1];
            }    
               else if(j==4){
                arr[i][j] = arr[i-1][j-1];
               }
            else{
                arr[i][j] = arr[i-1][j-1]+arr[i-1][j+1];
            }
        }
    }
    for(i=0;i<5;i++){
        for(j=0;j<5;j++){
            printf("%d ",arr[i][j]);
        }
        printf("\n");
    }
    return 0;
}
