If the array has duplicates output should be true, else return false if all the array elements are unique. Example: Input: Output: True Input: Output: False Method 1: By using set. As we know that, set contains only unique elements. Hence we insert all the …
Example 1: Input: hello Output: holle Example 2: Input: prodevelopertutorial Output: pradivolupertotereol We can solve this problem in 2 methods. Method 1: By using STL functions. In this method we use “find_first_of” and “find_last_of” find_first_of(“characters_to_search_for”, start_from_index) : It will return the position of the first …
