1208. Get Equal Substrings Within Budget

Leetcode Solutions

Sliding Window Approach

  1. Initialize two pointers i and j to 0 to represent the start and end of the sliding window, respectively.
  2. Initialize cost to 0 to keep track of the current cost of changing the substring.
  3. Iterate over the characters in s using the j pointer. a. Calculate the cost of changing s[j] to t[j] and add it to cost. b. While cost is greater than maxCost, subtract the cost of changing s[i] to t[i] from cost and increment i to shrink the window. c. Update the result with the maximum length of the window so far, which is j - i + 1.
  4. Return the result as the maximum length of the substring that can be changed within the given cost.
