Python Code

def solution(myString: str, pat: str) -> int:
    result = 0
    
    for x in range(len(myString) - len(pat) + 1):
        if myString[x:x+len(pat)] == pat:
            result += 1
    
    return result

Go Code

func solution(myString string, pat string) int {
    count := 0
    
    for i := 0; i <= len(myString)-len(pat); i++ {
        if myString[i:i+len(pat)] == pat {
            count++
        }
    }
    
    return count
}

Java Code

class Solution {
    public int solution(String myString, String pat) {
        int count = 0;
        for (int i = 0; i <= myString.length() - pat.length(); i++) {
            if (myString.substring(i, i + pat.length()).equals(pat)) {
                count++;
            }
        }
        return count;
    }
}
