### Consecutive elements

Level MEDIUM You are given an array arr of N non-negative integers, you need to return true if the array elements consist of consecutive numbers otherwise return false. 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
