Yet Another Two Integers Coding Question-Codeforces rated 1000

Problem Statement :

You are given two integers a and b.

In one move, you can choose some integer k from 1 to 10 and add it to a or subtract it from a. In other words, you choose an integer k∈[1;10] and perform a:=a+k or a:=a−k. You may use different values of k in different moves.

Your task is to find the minimum number of moves required to obtain b from a.

You have to answer t independent test cases.

Input Format:

The first line of the input contains one integer t (1≤t≤2*10^4) — the number of test cases. Then t test cases follow.

The only line of the test case contains two integers a and b (1≤a,b≤10^9).

Output Format:

For each test case, print the answer: the minimum number of moves required to obtain b from a.
