Leetcode Solutions

Using Slope Calculation to Determine Line Segments

  1. Sort the stockPrices array based on the day.
  2. Initialize a variable lines to 1, as at least one line is needed if there are at least two points.
  3. Calculate the initial slope between the first two points.
  4. Iterate over the remaining points starting from the third point.
  5. For each point, calculate the slope between the current point and the previous point.
  6. Compare the current slope with the previous slope.
  7. If the slopes are different, increment the lines counter and update the previous slope to the current slope.
  8. Continue until all points have been processed.
  9. Return the lines counter as the result.
