java - Algorithm for superdivide -

-

a int superdivide if every digit in number divides number. example 128 divides since 128 divisible 1, 2, , 8 superdivide number not divisible 0.

sample input #1  superdivide(184)  sample output #1  true  sample input #2  superdivide(39)  sample output #2  false  sample input #3  superdivide(120)  sample output #3  false

enter code here

public class superdivide {      public static void main(string[] args) {         superdivide obj = new superdivide();         boolean result = obj.checksuper(1001);         system.out.println(result);     }      public boolean checksuper(int num){         //write code here         int n1;         int n2=num;         if(num%10==0)         return false;         while(num>0){             n1=num%10;             if(n2%n1==0){                 num=num/10;                 return true;             }          }         return false;       }

above code runs fine upto digit number not 3digit,any suggestion?

maybe method should :

public boolean checksuper(int num) {     int n1;     int n2 = num;     while(num > 0) {         if(num % 10 == 0) {             return false;         }         n1 = num % 10;         if(n2 % n1 == 0) {             num = num / 10;         } else {             return false;         }     }     return true; }

i think work !

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
