Leetcode Problem 2145. Count the Hidden Sequences

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.
