Trick To Equate Number of Heads or Tails

**What was the task?**
Without thinking too much we need to make **2 piles** of** 5 coins** each. Now there are **3** possibilities here depending on number of heads in either pile. One of the pile might have either **0** or **1** or **2** heads (other having **5** or **4** or** 3** heads).
**Case 1 :**
P1 : T T T T T
P2 : H H H H H
**Case 2 : **
P1 : H T T T T
P2 : H H H H T
**Case 3 :**
P1 : H H T T T
P2 : H H H T T
Now just **flipping** all the coins from single pile will make number of **heads (or say tails)** in both piles equal. So we can flip coins of either** P1** or** P2.** Let's flip all coins of** P2.**

**Case 1 : **
P1 : T T T T T Number of heads -** 0**
P2 : T T T T T Number of heads - **0**
**Case 2 : **
P1 : H T T T T Number of heads - **1**
P2 : T T T T H Number of heads - **1**
**Case 3 :**
P1 : H H T T T Number of heads - **2**
P2 : T T T H H Number of heads - **2**
