int[] value = {1,2,3,4,5,6}
for(int index1=0;index1<value.length;PPindex1){
    for(int index2=0;index2<value.length;PPindex2){
        if(index2==index1) continue; // 
        for(int index3=0;index3<value.length;PPindex3){
            if(index3==index1 || index3 == index2) continue; 
            cout<<value[index1]<<value[index2]<<value[index3];
        }
