One.
Take out a number, divide it by the decimal point, divide it into two sections, and square it from the highest point.
Two people have a section, and the tallest one goes first.

The second step is the key!
Then take two more tablets.

Plus the maximum value that can be taken, what is the maximum value?
What about the big one? namely
x *(20+x)& lt； = 125
maximum

You can take 5.
,
It also happens to be 5
,
So the result of square root is 15.
Write cholesky decomposition.
