write a go solution for E. Three Stringstime limit per test2.5 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard outputYou are given three strings: a, b, and c, consisting of lowercase Latin letters. The string c was obtained in the following way:  At each step, either string a or string b was randomly chosen, and the first character of the chosen string was removed from it and appended to the end of string c, until one of the strings ran out. After that, the remaining characters of the non-empty string were added to the end of c.  Then, a certain number of characters in string c were randomly changed. For example, from the strings a=colorredabra and b=colorbluecada, without character replacements, the strings colorbluecacolorredabcolorbluedcolorredracolorbluea, colorredabracolorbluecada, colorredacolorbluecadacolorredbra could be obtained.Find the minimum number of characters that could have been changed in string c.InputThe first line of the input contains a single integer t (1<=t<=10^3) — the number of test cases.The first line of each test case contains one string of lowercase Latin letters a (1<=|a|<=10^3) — the first string, where |a| denotes the length of string a.The second line of each test case contains one string of lowercase Latin letters b (1<=|b|<=10^3) — the second string, where |b| denotes the length of string b.The third line of each test case contains one string of lowercase Latin letters c (|c|=|a|+|b|) — the third string.It is guaranteed that the sum of |a| across all test cases does not exceed 2*10^3. Also, the sum of |b| across all test cases does not exceed 2*10^3.OutputFor each test case, output a single integer — the minimum number of characters that could have been changed in string c.ExampleInput7abcbabcdacbdabbaaabbxxxyyyxyxyxyabcddecfcodeshorsecodeforceseggannieegaegaegOutput1
