Given an input string (s) and a pattern (p), implement wildcard pattern matching with support for '?' and '*' where:

  • '?' Matches any single character.
  • '*' Matches any sequence of characters (including the empty sequence).

The matching should cover the entire input string (not partial).

Example 1:

Input: s = "aa", p = "a"
Output: false
Explanation: "a" does not match the entire string "aa".

Example 2:

Input: s = "aa", p = "*"
Output: true
Explanation: '*' matches any sequence.

Example 3:

Input: s = "cb", p = "?a"
Output: false
Explanation: '?' matches 'c', but the second letter is 'a', which does not match 'b'.


  • 0 <= s.length, p.length <= 2000
  • s contains only lowercase English letters.
  • p contains only lowercase English letters, '?' or '*'.

Wildcard Matching in C++
class Solution {
  bool isMatch(string s, string p) {
    const int m = s.length();
    const int n = p.length();

    // dp[i][j] := true if s[0..i) matches p[0..j)
    vector<vector<bool>> dp(m + 1, vector<bool>(n + 1));
    dp[0][0] = true;

    auto isMatch = [](char c1, char c2) { return c1 == c2 || c2 == '?'; };

    for (int i = 0; i <= m; ++i)

Wildcard Matching in Java

    return dp[m][n];

  private boolean isMatch(char c1, char c2) {

Wildcard Matching in Python
class Solution:

    m = len(s)
    n = len(p)

    # dp[i][j] := true if s[0..i) matches p[0..j)
    dp = [[False] * (n + 1) for _ in range(m + 1)]
    dp[0][0] = True

    def isMatch(c1: chr, c2: chr) -> bool:
      return c1 == c2 or c2 == '?'

    for i in range(m + 1):
      for j in range(1, n + 1):
        if p[j - 1] == '*':
          matchEmpty = dp[i][j - 1]
          matchNew = i and dp[i - 1][j]
          dp[i][j] = matchEmpty or matchNew
          dp[i][j] = i and isMatch(s[i - 1], p[j - 1]) and dp[i-1][j-1]

    return dp[m][n]
