- Virus DNA files As a future doctor, Jojo works in a laboratory that analyzes viral DNA. Due to the pandemic During the virus outbreak, Jojo received many requests to analyze whether there was any viral DNA in the patient. This number of requests made Jojo's job even more difficult. Therefore, Jojo ask Lili who is a programmer for help to make a program that can read the file containing the patient's DNA data and viral DNA and then match them. If on the patient's DNA found the exact same string pattern, then write to the index screen the found DNA. Data contained in the file testdata.in Input Format The first line of input is the number of test cases TThe second row and so on as many as T rows are the S1 string of patient DNA and the S2 string of viral DNA separated by spaces Output Format The array index found the same string pattern.
