Java program to print the following pattern

Algorithm:

• STEP 1: START
• STEP 2: SET i=1,j=1,k=1,l=1,direction=1
• STEP 3: SET matrix[5][5]
• STEP 4: REPEAT STEP 5 to 9 UNTIL i is less than 5
• STEP 5: SET j=0
• STEP 6: REPEAT STEP 7 and 8 UNTIL j is less than 5
• STEP 7: SET matrix[i][j]=0
• STEP 8: SET j=j+1
• STEP 9: SET i=i+1
  // steps for printing the matrix
• STEP 10: SET i=0
• STEP 11: REPEAT STEP 12 to 16 UNTIL i is less than 5
• STEP 12: SET j=0
• STEP 13: REPEAT STEP 14 and 15 UNTIL j is less than 5
• STEP 14: PRINT matrix[i][j]
• STEP 15: SET j=j+1
• STEP 16: SET i=i+1
                //steps for snake
• STEP 17: SET i=1
• STEP 18: SET j=0
• STEP 19: SET k=0
• STEP 20: REPEAT STEP 21 to 26 UNTIL i is less than 16
• STEP 21: SET matrix[j][k]=i
• STEP 22: IF direction=1
                IF k+1<5
                IF matrix[j][k+1]==0
                SET k=k+1
                ELSE SET j=j+1 and SET direction =2
                ELSE SET j= j+1 and SET direction =2
• STEP 23: IF direction=2
                IF j+1<5
                IF matrix[j+1][k]==0
                SET j=j+1
                ELSE SET k=k-1 and SET direction =3
                ELSE SET k= -1 and SET direction =3
• STEP 24: IF direction=3
                IF k-1>=0
                IF matrix[j][k-1]==0
                SET k=k-1
                ELSE SET j=j-1 and SET direction =4
                ELSE SET j= j-1 and SET direction =4
• STEP 25: IF direction=4               IF j-1>=0
                IF matrix[j-1][k]==0
                SET j=j-1
                ELSE SET k=k+1 and SET direction =1
                ELSE SET k= k+1 and SET direction =1
• STEP 26: SET i=i+1
                // Steps for printing the matrix
• STEP 27: SET i=0
• STEP 28: REPEAT STEP 29 to 33 UNTIL i is less than 5
• STEP 29: SET j=0
• STEP 30: REPEAT STEP 31 and 32 UNTIL j is less than 5
• STEP 31: PRINT matrix[i][j]
• STEP 32: SET j=j+1
• STEP 33: SET i=i+1
• STEP 34: END
