Assist X怎么编辑出灰色代码

Answer 1

int[] triangle=null;
int[] tmp=null;
for (int i=0;i<10;i++){
if(i==0){
tmp = new int[1];
tmp[0]=1;
} else if (i==1){
tmp = new int[3];
tmp[0] = 1;
tmp[1] = 2;
tmp[2] = 1;
}
else {
tmp=new int [i+2];
tmp[0]=1;
for(int j=1;j<i+1;j++){
tmp[j]=triangle[j-1]+triangle[j];
}
tmp[tmp.length-1]=1;
}
triangle=tmp;
for(int j=0;j<triangle.length;j++){
System.out.print(tmp[j]);
System.out.print(" ");
}
System.out.println();
}
