// Given two strings a and b. The task is to find if the string 'b' can be obtained by rotating another string 'a' by exactly 2 places.

// Example 1:

// Input:
// a = amazon
// b = azonam
// Output: 1
// Explanation: amazon can be rotated anti
// clockwise by two places, which will make
// it as azonam.
// Example 2:

// Input:
// a = geeksforgeeks
// b = geeksgeeksfor
// Output: 0
// Explanation: If we rotate geeksforgeeks by
// two place in any direction , we won't get
// geeksgeeksfor.
