For Our task is to check for each string in the array if it can be formed using the characters of chars (we can use each character of char only once). If it is possible to construct the string using the characters of the chars string then add the length of the selected string into the result. In the end, we need to return the sum of the length of all the strings which can be formed using characters of chars string.eval(ez_write_tag([[250,250],'tutorialcup_com-medrectangle-3','ezslot_5',620,'0','0']));eval(ez_write_tag([[250,250],'tutorialcup_com-medrectangle-3','ezslot_6',620,'0','1'])); eval(ez_write_tag([[250,250],'tutorialcup_com-medrectangle-4','ezslot_7',632,'0','0'])); In this example, we can form hello and world using the characters of the chars string. Do this in-place, using the left side of the original array and maintain the relative order of the elements of the array. We will follow these steps to solve the problem: The time complexity of the above code is O(n*m) because we are traversing every character of all words. ) between some characters in the local name part of an email address, mail sent there will be forwarded to the same address without dots in the local name.
