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.
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.
For each test case output will be 1 if C is interleaving of string A and B else 0.
1<=length of A, B, C <=100
Example(To be used only for expected output):
YX X XXY
XY X XXY
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.
Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
