Given two strings *s* and *t*, return `true` if *t* is an anagram of *s*, and `false` otherwise. An anagram is a permutation of the letters of the other string.
s = "string1", t = "string2"
boolean (true/false)
Example 1:
Input:
s = "anagram" t = "nagaram"
Output:
true
Explanation:
t is a rearrangement of s.
Example 2:
Input:
s = "rat" t = "car"
Output:
false
Explanation:
t cannot be rearranged to form s.
