Leetcode Problem 2275. Largest Combination With Bitwise AND Greater Than Zero

2275. Largest Combination With Bitwise AND Greater Than Zero

Leetcode Solutions

Counting Set Bits at Each Position

  1. Initialize an array bitCounts of size 24 (since the maximum number in candidates is up to 10^7, which can be represented with 24 bits) to store the count of set bits at each bit position.
  2. Iterate over each number in candidates.
  3. For each number, iterate over each bit position from 0 to 23.
  4. If the bit at the current position is set (i.e., number & (1 << bitPosition) != 0), increment the count at that bit position in bitCounts.
  5. After processing all numbers, find the maximum value in bitCounts. This represents the largest combination size.
  6. Return the maximum value found in bitCounts.
