Yura is tasked to build a closed fence in shape of an arbitrary non-degenerate simple quadrilateral. He's already got three straight fence segments with known lengths a$a$, b$b$, and c$c$. Now he needs to find out some possible integer length d$d$ of the fourth straight fence segment so that he can build the fence using these four segments. In other words, the fence should have a quadrilateral shape with side lengths equal to a$a$, b$b$, c$c$, and d$d$. Help Yura, find any possible length of the fourth side.

A non-degenerate simple quadrilateral is such a quadrilateral that no three of its corners lie on the same line, and it does not cross itself.

Input

The first line contains a single integer t$t$ — the number of test cases (1≤t≤1000$1\le t\le 1000$). The next t$t$ lines describe the test cases.

Each line contains three integers a$a$, b$b$, and c$c$ — the lengths of the three fence segments (1≤a,b,c≤109$1\le a,b,c\le {10}^9$).

Output

For each test case print a single integer d$d$ — the length of the fourth fence segment that is suitable for building the fence. If there are multiple answers, print any. We can show that an answer always exists.

Note

We can build a quadrilateral with sides 1$1$, 2$2$, 3$3$, 4$4$.

We can build a quadrilateral with sides 12$12$, 34$34$, 56$56$, 42$42$.

Solution -

This Problem required a prerequisite about the property of a quadrilateral that is if you are given a three side of a quadrilateral let say a,b,c then it is sure that 4th side of the quadrilateral is smaller then a+b+c.

d<a+b+c

and this should hold true for all side of the quadrilateral. means

• a<b+c+d
• b<a+c+d
• c<a+b+d
• d<a+b+c

so by using this property we can print (a+b+c-1) as our ans because there can be multiple ans of this question and we have to print any one of them.

You can print another answer too which satisfy the above 4 conditions.
