474. Ones and Zeroes

Leetcode Solutions

Approach # Dynamic Programming

  1. Initialize a 2-D DP array dp with dimensions (m+1) x (n+1) filled with zeros.
  2. For each binary string s in the input list strs: a. Count the number of 0's (zeroes) and 1's (ones) in s. b. Iterate over the DP array from dp[m][n] to dp[zeroes][ones] in reverse order: i. Update dp[i][j] to be the maximum of dp[i][j] and 1 + dp[i - zeroes][j - ones].
  3. Return dp[m][n] as the result, which represents the size of the largest subset.
