Leetcode Problem 2550. Count Collisions of Monkeys on a Polygon

2550. Count Collisions of Monkeys on a Polygon

Leetcode Solutions

Calculating Collision Possibilities with Modular Exponentiation

  1. Initialize a variable mod to 10^9 + 7 for the modulo operation.
  2. Define a function modularExponentiation that takes a base a, an exponent b, and a modulo m, and computes a^b mod m using the square-and-multiply algorithm.
  3. In the monkeyMove function, call modularExponentiation with 2 as the base, n as the exponent, and mod as the modulo.
  4. Subtract 2 from the result of the exponentiation to account for the two collision-free scenarios.
  5. If the result is negative, add mod to ensure a positive result.
  6. Return the result modulo mod.
