Calculate Total Data Usage

You are given the data usage records of N customers over D days. For each customer, you need to compute the total data usage by summing up the usage over all days.

The data usage for the i-th customer can be calculated using the formula:

\( total\_usage_i = \sum_{j=1}^{D} usage_{ij} \)

The program should read the input from stdin and print the results to stdout, where each line of the output contains the customer id (starting from 0) followed by their total usage, separated by a space.

inputFormat

The first line of the input contains two integers N and D, representing the number of customers and the number of days respectively.

This is followed by N lines, each containing D integers. The j-th integer on the i-th line represents the data usage of customer i on day j.

Read the input from stdin.

outputFormat

For each customer, output a line containing two integers: the customer id and their total data usage. The output should be printed to stdout with each line formatted as:

customer_id total_usage
