link to spoj problem "blamoeba" i need help to complete this problem. i am stuck since last 2 days. solution was easy but i am not getting how to use modular inverse to calculate the final answer. answer — y/x = (m-1)*(m^n)/(m^n-1) (m^n means m to the power m) how to calculate the gcd of numerator and denominator before using modulo ?
according to me the answer should be
x = (m^n-1)/gcd
y = (m-1)*(m^n)/gcd
help me to do this or correct me if i am doing something wrong thanks in advance
