2861. Maximum Number of Alloys

Leetcode Solutions

Binary Search on Maximum Number of Alloys

  1. Initialize a variable maxAlloys to keep track of the maximum number of alloys that can be created across all machines.
  2. Iterate over each machine's composition.
  3. For each machine, perform a binary search to find the maximum number of alloys that can be created: a. Set the low end of the search range to 0 and the high end to a large number (e.g., 1e9). b. While the low end is less than or equal to the high end: i. Calculate the mid-point of the search range. ii. Check if it's possible to create mid alloys with the current machine within the budget. iii. If it is possible, update the low end to mid + 1 and set maxAlloys to mid if it's greater than the current maxAlloys. iv. If it's not possible, update the high end to mid - 1.
  4. Return the value of maxAlloys.
