Taco Transformation Instructions

Given two integers startID and targetID, your task is to compute the minimum number of instructions needed to transform startID into targetID. In each move, you are allowed to either increment (+1) or decrement (-1) the current value. Mathematically, the minimum number of instructions is given by the formula: \( |targetID - startID| \).

The input consists of multiple test cases. For each test case, you need to output the computed number of instructions on a new line.

inputFormat

The first line of the input contains a single integer \( T \) representing the number of test cases. Each of the next \( T \) lines contains two space-separated integers: startID and targetID.

outputFormat

For each test case, output a single line containing the minimum number of instructions required to convert startID to targetID.
