Question: Let N be an n-bit positive integer, and let a, b, c, and k be positive integers less than N. Assume that the multiplicative inverse

Let N be an n-bit positive integer, and let a, b, c, and k be positive integers less than N. Assume that the multiplicative inverse (mod N) of a is a^k-1.

Give an O(n³) algorithm for computing a^{(b^c)} mod N (i.e., a raised to the power b^c with the result taken mod N). Any solution that requires computing b^c is so inefficient that it will receive no credit.
