Leetcode Problem 2436. Minimum Split Into Subarrays With GCD Greater Than One

2436. Minimum Split Into Subarrays With GCD Greater Than One

Leetcode Solutions

Greedy Approach with GCD Calculation

  1. Initialize count to 1, as we will have at least one subarray.
  2. Initialize current_gcd with the first element of the array.
  3. Iterate through the array starting from the second element. a. Calculate the GCD of current_gcd and the current element. b. If the GCD is 1, increment count, and set current_gcd to the current element (start a new subarray). c. Otherwise, continue with the next element.
  4. Return the count as the minimum number of subarrays needed.
