Our main function character array will be declared and initialized with an index size of 50 (assuming this size will be enough for this example). After array declaration, we will store user input in our newly declared array variable using the gets function (gets function is used for fetching ...
Splits the elements of a sequence into chunks of size at most size. Concat<TSource>(IEnumerable<TSource>, IEnumerable<TSource>) Concatenates two sequences. Contains<TSource>(IEnumerable<TSource>, TSource, IEqualityComparer<TSource>) Determines whether a sequence contains a specified element by...
