// While debugging :
// 1 : check if array size is correct  :  It may give unexpected results
// 2 : check if you have swapped i and j at some part of program
// 3 : for string check if you are trying to acces  index = -1


// Bitwise Tricks :
// 1 : While using 1<<i  use (ll)1<<i  because in former one "1" is considered as int
// 2 : To flip first k-bits of a number :  x xor (2^k-1)  or x ^ (((ll)1<<k)-1)  : 2^k-1 is the largest number of k bits
// 3 : To flip k-th bit (0-based)  :  x xor (2^k)  or  x ^ ((ll)1<<k)
// 4 : To set k-th bit (0-based)   :  x or (2^k)   or  x | ((ll)1<<k)
// 5 : To un-set k-th bit (0-based)   :  x & (~ ((ll)1<<k) )


// To prove Greedy :
// 1 : Optimal Choice at each step
// 2 : Exchange Argument
// 3 : Find a lower or upper bound on answer and then construct an answer for that bound
// 4 : Find properties which Optimal Solution must satisfy ( This can be useful to deduce form of Optimal answer)
