写合约的时候遇到了如标题的这个问题，自己找不出问题，想问一下怎么解决

 function Shapley_A1_VS_rest() public view returns (uint[] memory m){
        uint len;
        uint temp=0;
        uint temp_VS;
        uint temp_VS_A1;
        for(len=0;len<VS_A1.length;len++){
            temp_VS=VS[len];
            temp_VS_A1=VS_A1[len];
            temp=temp_VS-temp_VS_A1;
            VS_A1_rest.push(temp);
        }
        m =  new uint[](VS_A1_rest.length);
        for(uint i = 0; i < VS_A1_rest.length; i++){
            m[i] = VS_A1_rest[i];
        }
    }
