Modular Multiplicative Inverse | Practice | GeeksforGeeks | Given two integers ‘a’ and ‘m’. The task is to find the smallest modular multiplicative inverse of ‘a’ under modulo ‘m’.
Example 1:
Input:
a = 3
m = 11
Output: 4
Explanation: Since (4*3) mod 11 = 1, 4
is modulo inverse of 3. One might think,
15 also as a valid output as "(15*3)
mod 11" is also 1, but 15 is not in
