Remove Consecutive Duplicates
If the input string is ‘str’ = ”aazbbby”, then your output will be “azby”. Note that we are just removing adjacent duplicates.
The first line of input contains an integer 'T' representing the number of test cases. The first line of each test case contains a single integer ‘N’ denoting the size of the given string. The second line of each test case contains a string of size ‘N’.
For each test case, print the new string that doesn’t have consecutive duplicates. The output of each test case will be printed in a separate line.
1 <= T <= 5 1 <= N <= 1000 Where ‘T’ is the number of test cases, ‘N’ is the length of the given string, and the given string contains only lowercase English letters.
You do not need to print anything, it has already been taken care of. Just implement the given function.
