Create an algorithm and write a program that chooses the largest of two given positive numbers X, Y.

The point of choosing the largest number is that we compare them.
For example, we can create a variable and assign it the value of the variable that is entered first:
var x, y, naibolshee: integer;
begin
naibolshee: = x;
And then, depending on whether the new entered variable is greater or less, we reassign the value of the largest variable to the variable of the two that is greater.
That is, if the second is less, then we do nothing and end the program, if it is more, we perform the following operation:
naibolshee: = y;
end.
