You are given two strings of the same length s1 and s2 and a string baseStr.
We say s1[i] and s2[i] are equivalent characters.
s1 = "abc" and s2 = "cde", then we have 'a' == 'c', 'b' == 'd', and 'c' == 'e'.Equivalent characters follow the usual rules of any equivalence relation:
\n\n'a' == 'a'.'a' == 'b' implies 'b' == 'a'.'a' == 'b' and 'b' == 'c' implies 'a' == 'c'.For example, given the equivalency information from s1 = "abc" and s2 = "cde", "acd" and "aab" are equivalent strings of baseStr = "eed", and "aab" is the lexicographically smallest equivalent string of baseStr.
Return the lexicographically smallest equivalent string of baseStr by using the equivalency information from s1 and s2.
\n
Example 1:
\n\n\nInput: s1 = "parker", s2 = "morris", baseStr = "parser"\nOutput: "makkek"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [m,p], [a,o], [k,r,s], [e,i].\nThe characters in each group are equivalent and sorted in lexicographical order.\nSo the answer is "makkek".\n\n\n
Example 2:
\n\n\nInput: s1 = "hello", s2 = "world", baseStr = "hold"\nOutput: "hdld"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [h,w], [d,e,o], [l,r].\nSo only the second letter 'o' in baseStr is changed to 'd', the answer is "hdld".\n\n\n
Example 3:
\n\n\nInput: s1 = "leetcode", s2 = "programs", baseStr = "sourcecode"\nOutput: "aauaaaaada"\nExplanation: We group the equivalent characters in s1 and s2 as [a,o,e,r,s,c], [l,p], [g,t] and [d,m], thus all letters in baseStr except 'u' and 'd' are transformed to 'a', the answer is "aauaaaaada".\n\n\n
