first and last digit codechef solution

t=int(input())
for i in range(t):
    x=str(input())
    a=int(x[0])
    b=int(x[-1])
    c=a+b
    print(c)

First and Last Digit codechef solution in c++

#include<iostream>

// Get first number
int first_number(int n)
{
	while (n > 9)
	{
		n /= 10;
	}
	return n;
}
// Get last number
int last_number(int n)
{
	return n %= 10;
}

{
	int t, n, sum;
	cin >> t;
	for (int i = 0; i < t; i++)
	{
		cin >> n;
		sum = 0;
		sum = first_number(n) + last_number(n);
		cout << sum << "
";
	}
	return 0;
