Algorithm

STEP 1: START
STEP 2: SET lines=8, i=1,j=1,k=1
STEP 3: REPEAT STEP 4 to 13 UNTIL i is less than lines
STEP 4: SET j=1
STEP 5: REPEAT STEP 6 and 7 UNTIL j is less than or equals to (lines/2)
STEP 6: IF j is equals to i PRINT j
ELSE IF i is greater than 4 and j equals lines-i PRINT j
ELSE PRINT " "
STEP 7: j = j + 1
STEP 8: j = j - 2
STEP 9: REPEAT STEP 10 and 11 UNTIL j is greater than 0
STEP 10: IF j is equals to i PRINT j
ELSE IF i is greater than 4 and j equals lines-i PRINT j
ELSE PRINT " "
STEP 11: j = j - 1
STEP 12: PRINT a new line
STEP 13: i = i + 1
STEP 14: EXIT

C Program:

#include <stdio.h>  
int main()  
{  
    int lines=8;  
    int i,j,k;  
    for(i=1;i<lines;i++){// this loop is used to print the lines  
        for(j=1;j<=lines/2;j++){// this loop is used to print numbers  
            if(i==j){  
                printf("%d",j);     
            }  
            else if(i>4 && j==lines-i){  
                printf("%d",j);     
            }  
            else{  
               printf(" ");   
            }              
        }  
        j=j-2;  
        while(j>0){  // this loop is used to print numbers  
            if(i==j){  
            printf("%d",j);     
            }  
            else if(i>4 && j==lines-i){  
                printf("%d",j);     
            }  
            else{  
                printf(" ");   
            }  
             
            j--;  
        }  
        printf("\n");  
    }  
   return 0;  
}

Output:

Java Program:

public class pattern{
