for循环，斐波那契数列为例

contract HelloFor {

    uint[] public arr = [1,1];

    function getarr() public view returns(uint[] memory){
        return arr;
    }

    //斐波那契数列
    //1,1,2,3,5,8,13,21,34,55,89,144
    function f() public {

        for(uint i=0;i<10;i++){
            uint a = arr[arr.length-1];
            uint b = arr[arr.length-2];
            uint c = a+b;
            arr.push(c);
