function combination(m,n){
    if(n == 0) return 1;//第一个数为1
    else if(m == n) return 1; //最后一个数为1
    else return combination(m-1,n-1)+combination(m-1,n);//中间的数为前一行的两个数相加
}
function Print(n){ 
    for( var i = 0 ; i <p><span class="img-wrap"><img src="https://img.php.cn//upload/image/838/629/233/1547689738622346.png" title="1547689738622346.png" alt="JavaScript code example to implement Yang Huis triangle"></span></p><p class="comments-box-content"></p>
