On planet zorba, a solar blast has melted the ice caps on its
equator. 8 years after the ice melts, tiny plantoids called echina start
growing on the rocks. echina grows in the form of a circle and the
relationship between the diameter of this circle and the age of echina
is given by the formula
d = 4 * sqrt (t – 8)for t = 8
Where the represents the diameter in mm and t the number of years since
the solar blast.
Jagan recorded the time of some echina at a particular spot is 24 years
then what is diameter?
36 people {a1, a2, ..., a36} meet and shake hands in a circular
fashion. In other words, there are totally 36 handshakes involving the
pairs, {a1, a2}, {a2, a3}, ..., {a35, a36}, {a36, a1}. Then size of the
smallest set of people such that the rest have shaken hands with at
least one person in the set is.
