Birthday paradox

#1 
    double p;
	cin>>p;
	int ans = ceil(sqrt(730.0*(log(1/(1-p)))));
	cout<<ans<<endl;

why is this code failing on HB for birthday paradox??(only 6th testcase)

@shameek.agarwal
code gives wrong output when the input is 1
the answer is 367

garbage value is being displayed
add a boundary condition if input is 1

for those not getting…expected answer is 366 for 1 (simple pigeonhole)…if 366 people then surely some two people will have birthday on the same day
