If anyone ever asks for what good are 'lambda' and 'reduce', show them
this...
print (lambda p:p[0]+'.'+p[1:])(
str((lambda(x,y,t,a):2L*x*x//a)(
(lambda F:(lambda S:reduce(
lambda(x,y,t,a),_:((x+y)//2L,
S((x*y)//F),2L*t,
(a-(t*(((x+y)//2L)**2-
(S((x*y)//F))**2))//F)),
[0]*13,(F,(F*F)//S(2L*F),2L,F//2L)))(
lambda n:reduce(lambda x,_:(
x-x//2L+(n*F)//(2L*x)),
[0]*15,
n//2L)))(10L**(5010))))[:5000])
You have to be a bit patient with this one...
