Tosolve the duplicate keys issue,we canpass a merge function to thetoMap()methodas the third parameter to handle the values associated with the duplicate keys. We may have different merge requirements for the duplicate keys scenario. In our example, we would like topick the higher score once ...
TheArray.prototype.concat()built-in function can be used to create a custom flattening function. Theconcat()function merges two or more arrays into one, and it can be used to flatten an array that is one level deep. Here’s an example of how we can achieve this: ...
Python program to flatten only some dimensions of a NumPy array # Import numpyimportnumpyasnp# Creating a numpy array of 1sarr=np.ones((10,5,5))# Display original arrayprint("Original array:\n", arr,"\n")# Reshaping or flattening this arrayres1=arr.reshape(25,10) res2=arr.reshape(...
In the constructor, we push all the nestedList into the stack from back to front, so when we pop the stack, it returns the very first element. Second, in the hasNext() function, we peek the first element in stack currently, and if it is an Integer, we will return true and pop the...

The apply() method is a part of concat() function's prototype that calls the function with a given this value, and arguments provided as an array.Alternatively, you could use the ES6 syntax to make the above example super concise:
How do you flatten array in javascript If you are given an array that contains literals, arrays and objects and you want to get all the values to one array. Here is the snippet using recursive function to attain that. functionimplode(arr){varres = [];for(vari =0; i < arr.length ;...
