Question

编程：求100-999之间的所有水仙花数。

Answer 1

LOCAL lnI,lcZf,lnGw,lnSw,lnBw

FOR lnI=100 to 999

lcZf=ALLTRIM(STR(m.lnI))

lnGw=VAL(SUBSTR(m.lcZf,3,1))

lnSw=VAL(SUBSTR(m.lcZf,2,1))

或者

#include<stdio.h>

void main()
{
int n = 100;
int a;
int b;
int c;
for( n=100;n<=999;n++)
{
a = n/100;
b = n/10%10;
c = n%10;
if ( n==(a*a*a+b*b*b+c*c*c))
{
printf("%d %d %d\n",a,b,c);

lnBw=VAL(SUBSTR(m.lcZf,1,1))

IF m.lnGw^3+m.lnSw^3+m.lnBw^3=m.lnI then

?m.lnI

ENDIF

ENDFOR

Answer 2

for(int a=100, a<1000, a++){
if((a/100+a%100/10+a%100%10)==a)
System.out.pritnln(a);
}
