2145. Count the Hidden Sequences

Leetcode Solutions

Calculating the Range of Possible Hidden Sequences

  1. Initialize variables to keep track of the running sum (current_sum), the minimum value (min_value), and the maximum value (max_value) of the hidden sequence.
  2. Iterate through the differences array, updating current_sum, min_value, and max_value accordingly.
  3. Calculate the adjusted minimum (adjusted_min) and maximum (adjusted_max) values by adding lower to min_value and upper to max_value.
  4. If adjusted_max is less than lower or adjusted_min is greater than upper, return 0 as no sequences are possible.
  5. Otherwise, calculate the number of possible sequences as adjusted_max - adjusted_min + 1 and return this value.
