Problem Statement

You are given strings S and T consisting of lowercase English letters.

You can perform the following operation on S any number of times:

Operation: Choose two distinct lowercase English letters c_1 and c_2, then replace every occurrence of c_1 with c_2, and every occurrence of c_2 with c_1.

Determine if S and T can be made equal by performing the operation zero or more times.

Constraints

1 \leq |S| \leq 2 \times 10^5

|S| = |T|

S and T consists of lowercase English letters.

Input

Input is given from Standard Input in the following format:

S
T

Output

If S and T can be made equal, print Yes; otherwise, print No.

Sample Input 1

azzel
apple

Sample Output 1

azzel can be changed to apple, as follows:

Choose e as c_1 and l as c_2. azzel becomes azzle.

Choose z as c_1 and p as c_2. azzle becomes apple.

Sample Input 2

chokudai
redcoder

Sample Output 2

No

No sequences of operation can change chokudai to redcoder.

Sample Input 3

ibyhqfrekavclxjstdwgpzmonu

Sample Output 3

Yes

Solution in C++ (GCC 9.2.1) (judge verdict: Accepted)

#include <bits/stdc++.h>
#define REP(i, n) for (int i = 0; i < (n); i++)
using namespace std;

int main() {
	cin.tie(0)->sync_with_stdio(false);

	string S, T; cin >> S >> T;
	int n = S.size();

	vector<char> cntS(26, 0), cntT(26, 0);
	REP(i, n) {
		cntS[S[i]-'a']++;
		cntT[T[i]-'a']++;
		if (cntS[S[i]-'a'] != cntT[T[i]-'a']) {
			cout << "No" << '\n';
			return 0;
		}
	}

	cout << "Yes" << '\n';
	return 0;
}
