You have three strictly uncorrelated HFT alpha signals with identical expected returns, but their variances are 1, 2, and 3. You need to fully allocate $10 million across them to minimize total variance, with no shorting. Without writing out complex KKT conditions, can you directly compute the exact dollar allocation?

你有三个完全不相关的高频交易Alpha信号，历史回测预期收益一样，但方差分别是1、2和3。现在有1000万资金要求满仓分配给它们以最小化总方差，禁止做空。不写复杂的KKT条件，你能直接口算告诉我具体的资金分配数额吗？
