emergency

Note
sqrt(10)=3.16227.
In addition to 101001000,... And
3,31,316,3162,31622,...
Namely
3,10,31,100,316,1000,3162,.
1-3,1 * 3 = 3 bits
4-10,2 * 7 = 14 bits
11-31,3 * 21 = 63 bits
32-100,4 * 69 = 276 bits
3 + 14 + 63 = 80 bits, the 200th bit is between 32-100
(200-80) = 120 bits
120/4=30
Therefore, the 200th bit is the last bit of the square of 31 + 30 = 61, i.e. 1
