题目描述
The National Championships are starting soon. There are 4 race categories, numbered from 1 to 4, that Chef is interested in. Chef is participating in exactly 2 of these categories.
Chef has an arch-rival who is, unfortunately, the only person participating who is better than Chef, i.e, Chef can't defeat the arch-rival in any of the four race categories but can defeat anyone else. Chef's arch-rival is also participating in exactly 2 of the four categories.
Chef hopes to not fall into the same categories as that of the arch-rival.
Given X, Y, A, B where X, Y are the races that Chef participates in, and A, B are the races that Chef's arch-rival participates in, find the maximum number of gold medals (first place) that Chef can win.
------ Input Format ------
- The first line of input contains an integer T, denoting the number of testcases. The description of T testcases follows.
- Each testcase consists of a single line containing four space-separated integers — the values of X, Y, A, and B respectively.
------ Output Format ------
- For each testcase, print a single line containing one integer — the maximum number of gold medals that Chef can win.
------ Constraints ------
$1 ≤ T ≤ 144$
$1 ≤ X, Y, A, B ≤ 4$
$X \neq Y$
$A \neq B$

Test case $1$: Chef participates in the races $4, 3$, whereas Chef's rival participates in $1, 2$. As Chef's only rival does not participate in any of the races that Chef takes part in, Chef can win the gold medal in both of the races, thus the answer is $2$.
Test case $2$: Chef participates in the races $4, 2$, whereas Chef's rival participates in $1, 2$. Chef cannot win race $2$ as Chef will be beaten by the arch-rival, however Chef can win the gold medal for race $4$. Thus the answer is $1$.
Test case $3$: Chef participates in the races $2, 1$, whereas Chef's rival participates in $1, 2$. Chef will be beaten by the arch-rival in both races, thus the answer is $0$.
