The given Python code snippet demonstrates the use of a lambda function and the map() function to square each element in the list `numbers`. The output of the code will be a list of squared numbers: `[1, 4, 9, 16]`.The functional programming feature demonstrated here is the use of higher-order functions. The `map()` function takes a lambda function as an argument and applies it to each element in the input list. The lambda function takes a single argument `x` and returns the result of squaring `x`. By using `map()` with a lambda function, we can apply the same operation (squaring) to each element in the list without using a for loop or nested loops. This is a common technique in functional programming to perform operations on collections of data in a concise and efficient manner.
