// A mountain shepherd, wants to send special winter greetings to his fellow shepherds in nearby villages. However, his list of greetings is all combined into a single string using various symbols as separators, such as '.' , '@', '!' etc. Your task is to help him separate these strings into individual greetings so he can send them out clearly.

// Input Format

// The first line will be T, the number of test cases.
// Each test case will provide a single string containing greetings combined with special characters.
// Constraints

// 1≤ T≤ 500
// 1 ≤ S.size() ≤ 1000
// S contains alphanumeric characters and special symbols: {~,!,@,#,$,%,^,&,*,(,),_,+}
// Output Format

// For each test case, output the list of separated strings containing greetings.

// Sample Input 0

// 1
// warm@winter!greetings_to_you
// Sample Output 0

// warm
// winter
// greetings
// to
// you
