Minimum Substring Length Containing Characters

Given two strings s and t, write a function to find the minimum length of a substring of s that contains all the characters in t (including duplicates). If there is no such substring, return 0. For example, for the input s = "ADOBECODEBANC" and t = "ABC", the output should be 4 because the minimum substring is "BANC". Input Format: - The first line contains the string s. - The second line contains the string t. Output Format: - A single integer indicating the minimum length of a substring of s that contains all characters in t. Example: Input: ADOBECODEBANC ABC Output: 4
