min no: of races required is 7..
That is correct dude
do u mind explaining.....
ok.. first divide the 25 horses into 5 grps a,b,c,d,e and conduct the race.. let a1 be the horse tat comes first in grp a, a2 be the horse tat comes second and so on..
now grp a1,b1,c1,d1,e1 together and conduct a race. let a1 be the winner of this. so u got the first place horse.. let b1 and c1 be 2nd and ed in this race.
now u need to find the second and third place horse. we r sure tat the grp d and e does nt contain the horse.
so the 2nd and third place winners maybe 2 of a2,a3,b1,b2,c1
So race them together and u will get the 2nd and 3rd place winner.
will type a better solution later :D hope this is ok..
That is the best solution ..
is there anything better?
i was talkin abt my explanation.. i typed it in a hurry :D
thanks da....
u r welcome :)
