Problem Statement

#### For Example: If the given array is [4,3,5] then you should return true as all the array elements are in consecutive order.

##### Input Format:
``````The first line of input contains a single integer T, representing the number of test cases or queries to be run.
Then the T test cases follow.

The first line of each test case contains an integer 'N', representing the length of the array.

The next line contains 'N' single space-separated integers representing elements of the array.
``````
##### Output Format :
``````For each test case, print “True” or “False” in a separate line.
``````
##### Note:
``````You are not required to print the expected output, it has already been taken care of. Just implement the function.
``````
##### Constraints:
``````1 <= T <= 10
1 <= N <= 10^5
0 <= arr[i] <= 10^9

Time Limit: 1 sec
``````
##### Sample Input 1:
``````1
4
1 2 4 6
``````
##### Sample Output 1:
``````False
``````
##### Explanation for Input 1:
``````As 3 and 5 are not in the array. Thus, this makes the array non-consecutive.
``````
##### Sample Input 2:
``````1
3
7 9 8
``````
##### Sample Output 2:
``````True
