We have two dots \$d_1,d_2\$ moving on circles \$C_1, C_2\$ with radii \$r_1, r_2\$. The circles are moving at speed of \$s_1, s_2\$. A line is drawn between \$d_1\$ and \$d_2\$. When does this line have some segment inside the smaller of the two circles? There is some code here.

I do not think it is needed, so I have removed it.

Let \$x=(x_1,x_2,\ldots,x_n)\$ be an \$n\$-tuple where \$n\$ is even In how many ways we can arrange such that exactly half of the entries are even ? My attempt is : As we are talking about possible arrangements where order doesn't matter, so we will use combination, not permutation. So for \$n/2 =...
