compare towers

[aleksandr421]

my code fails the tests
Ten towers are given. You need to compare them. exponentiation occurs from right to left a ^ (a ^ (a ^ a)). At the end, print their indexes in ascending order. Here is my code but it is incorrect.
input
10 // number of towers
4 2 2 2 2 2 // 4 The first number in a line is not an element of the tower, it is the //number of elements in it minus one.
1 2 2
1 3 2
1 2 3
3 2 2 2 2
2 2 2 2
1 3 3
3 3 3 3 3
2 4 3 3
2 2 3 4
output
2 4 3 6 7 5 9 10 1 8
