WebTo check if an array is symmetric or not, we need to compare the first half of the array with the reverse second half of array. For this, we are going to use the std::equal () function from STL. In this function, we will pass three arguments, Advertisements. A pointer, pointing to the start of array i.e. arr.
WebJul 2, 2024 · I'll attempt an intuitive explanation: to compare any one string of length m against another string of length n, there is a 1/max (n, m) chance that the strings are equal length. If the strings are equal length, then comparing them is linear. So the expected runtime would be O (1/max (n, m) * n) or simply O (n). jtschoonhoven Jul 3, 2024 at 1:22 triple screening embarazoWebMar 15, 2011 · It doesn't work with std::string , but string has a member function called compare that can take std::string and cstrings.
