You just split the 20 coins into two groups such that each one contains 10 coins. Now you have to flip any one group of coins so that you will get same no. of heads and tails in each group.
For example,consider the 1st group contains 7 heads and 3 tails so obviously the 2nd one contains 7 tails and 3 heads. if you flip the 2nd group coins means you will get 7 heads and 3 tails so each group contains same no. of heads and tails. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
