The Stack data structure can be used to solve this problem, following are the steps :-. const output = [17, 12, 354, 1]; Therefore, let's write the code for this function . I had written a program to reduce a string as much as possible by following rule for example "aabccddd" just remove the adjacent letters with same value as much as possible aabccddd -> bccddd bccddd -> bddd bddd -> bd Suppose while reducing atlast you get bb -> print empty string for that scenario.. Below is the C++ implementation of the above idea. You're not passing new_list as a parameter to the recursive function; therefore, each level of the recursion is unaware of the results you have gathered so far, and the result of the recursion is only the result of the first level.
