CodeChef: Practical coding for everyone.
My this solution got accepted, but this do not took care of right to left precedence of ‘^’… try this : 1 5 a^b^c output should be abc^^. which is not.
I fixed it here but it is showing wrong answer.

help.
Precedence of ^ is left to right
check at the end of this page (Operator Precedence and Associativity in C - GeeksforGeeks)
How do we know this ‘^’ is xor not ‘^’ exponentiation operator?
Try converting them here.

^ is xor operator in programming (it is exponentiation operator in mathematics). Problem setter should have mentioned this.
