![]() Because we were able to convert to by performing exactly operations, we print Yes. Next, we perform append operations (i.e., a, b, and a). We perform delete operations to reduce string to the empty string (recall that, though the string will be empty after deletions, we can still perform a delete operation on an empty string to get the empty string). Next, we perform append operations (i.e., r, a, n, and k), to get hackerrank. We perform delete operations to reduce string to hacker. Print Yes if you can obtain string by performing exactly operations on. and consist of lowercase English alphabetic letters.The third line contains an integer, the number of operations. The second line contains a string, the desired final string. The first line contains a string, the initial string. k: an integer that represents the number of operations.It should return a string, either Yes or No.ĪppendAndDelete has the following parameter(s): If there were fewer than moves, we would not have succeeded in creating the new string.Ĭomplete the appendAndDelete function in the editor below. If there had been more moves available, they could have been eliminated by performing multiple deletions on an empty string. On the move, you will have the matching string. Next we add each of the characters of in order. To convert to, we first delete all of the characters in moves. Otherwise, print No.įor example, strings and. ![]() ![]() Given an integer,, and two strings, and, determine whether or not you can convert to by performing exactly of the above operations on. Performing this operation on an empty string results in an empty string. Delete the last character in the string.Append a lowercase English alphabetic letter to the end of the string.You can perform two types of operations on the string: You have a string of lowercase English alphabetic letters.
