Given three strings A, B and C your task is to complete the function **isInterleave** which returns true if C is an interleaving of A and B else returns false. C is said to be interleaving A and B, if it contains all characters of A and B and order of all characters in individual strings is preserved.

**Input:**

The first line of input contains an input T denoting the no of test cases. Then T test cases follow. Each test case contains three space separated strings A, B, C.

**Output:**

For each test case output will be 1 if C is interleaving of string A and B else 0.

**Constraints:**

1<=T<=100

1<=length of A, B, C <=100

**Example(To be used only for expected output):
Input:**

2

YX X XXY

XY X XXY

0

1

1. For first test case XXY is not interleaving of YX and X

2. For the sec test case XXY is interleaving of XY and X.
