Bubble sort and narcissus algorithm and 99 multiplication table

99 Multiplication Table:

please use algorithmic program to make 99 multiplication table. ()

.

Its corresponding algorithm is

1  Public class99 multiplication Table {2      Public Static voidMain (string[] args) {3          for(inti=1;i<=9;i++){4              for(intj=1;j<=i;j++){5                 inta=i*J;6System.out.print (i+ "*" +j+ "=" +a+ "");7             }8 System.out.println ();9         }Ten     } One}

Bubble Sort:

　Before bubbling the sort, look at a simple arrays method of sorting, the program is as follows:

1  Public Static voidMain (string[] args) {2         //first define an array3         int[] a={23,90,9,25,16,2};4 Arrays.sort (a);5          for(inti=0;i<a.length;i++) {6System.out.println (a[i]+ "");//positive sequence output, and from small to large7System.out.print (a[a.length-1-i]+ "");//reverse output, and from large to small8         }9}

　　Now there are 23,90,9,25,16,2 these six numbers, please use Bubble Sort the algorithm arranges the size.

1  Public classBubble Sort {2      Public Static voidMain (string[] args) {3         //first define an array4         int[] num={23,90,9,25,16,2};5         intTemp=0;6          for(inti=0;i<num.length-1;i++){7              for(intj=0;j<num.length-1-i;j++){8                 if(Num[j]<num[j+1]) {//change the smaller to greater than the number is small to large row9temp=Num[j];TenNum[j]=num[j+1]; Onenum[j+1]=temp; A                 } -             } -         } the         //Final Loop Output -          for(inti:num) { - System.out.println (i); -         } +     } -}

　　the classic algorithm in Java, Narcissus algorithm :

Find the number of daffodils in 100-999, (if three digits abc,abc=a^3+b^3+c^3, it is called ABC is the number of daffodils.) such as 153,1^3+5^3+3^3=1+125+27=153, then 153 is the number of daffodils)!

1  Public classNarcissus algorithm {2         Static intA;3         Static intb;4         Static intC;5         Static intsum;6     7      Public Static voidMain (string[] args) {8         /*the number of daffodils in 100-999, (if three digits of abc,abc=a^3+b^3+c^3,9 the number of daffodils is called ABC. such as 153,1^3+5^3+3^3=1+125+27=153, then 153 is the number of daffodils)!*/Ten          for(inti=100;i<=999;i++) {//153 OneA=i%10; AB=i/10%10; -c=i/100; -sum=a*a*a+b*b*b+c*c*C; the             if(sum==i) { -System.out.println (i+ "is narcissus number!!")); -             }     -         } +     } -}
