1981. Minimize the Difference Between Target and Chosen Elements

Leetcode Solutions

DP + Memoization

  1. Initialize a memoization table dp with default values indicating uncalculated states.
  2. Define a recursive function solve that takes the current row index row and the current sum sum as arguments.
  3. If row is equal to the number of rows in the matrix, return the absolute difference between sum and target.
  4. If the current state has been calculated before (i.e., dp[row][sum] is not the default value), return the stored result.
  5. Initialize a variable minDiff to store the minimum absolute difference found so far.
  6. Iterate over each element in the current row and recursively call solve for the next row with the updated sum.
  7. Update minDiff with the minimum value returned by the recursive calls.
  8. Store the calculated minDiff in the memoization table before returning it.
  9. Call solve starting from the first row and a sum of 0.
  10. Return the result of the initial call to solve.
