Snake Case to Camel Case Conversion

You are given a list of variable names in snake_case format. Your task is to convert each of these names into camelCase format according to the following rules:

• The first word remains in lowercase.
• For each subsequent word, the first letter is capitalized while the rest remain in lowercase.

For example, converting hello_world yields helloWorld.

You need to read the input from standard input (stdin) and output the results to standard output (stdout), with each converted name printed on a new line.

inputFormat

The first line contains an integer n, the number of variable names. The next n lines each contain a single string representing a variable name in snake_case format.

outputFormat

Output n lines, each containing the corresponding variable name converted to camelCase.
