Description Ramesh is given an integer n and a string num. He has to create the smallest number possible by removing n digits from num (the removed digits may or may not be contiguous). The value returned must also be a string. For example. If Ramesh has num = "1432219" and n = 3, then we must remove the digits 4, 3, and 2 to get the smallest value i.e. "1219", It should be noted that if after removing n digits, the num is empty, you must return "0". In addition, all leading zeros must be removed before returning the string. Can you help Ramesh find a solution to this problem? Input Format - The first line in input is n and the second line contains a string. Output Format - Output is a string with the smallest possible value. Constraints The first line inputs an integer n and the second line inputs a string num. The length of num is denoted by len. 0 <= n <= len 1 <= len <= 200,000 • Num may contain leading zeros.
