In Swift, a dictionary is an unordered collection in which data is stored in the form of key-value pairs, where keys are the unique identifiers. So to check the equality of two dictionaries we first need to check if the size of both the dictionaries is equal or not. If yes, then we check if both dictionaries contain the same key-value pairs or not. If both conditions are equal, then that means the given two dictionaries are equal. If any of the conditions are false then that means the given dictionaries are not equal. Algorithm Step 1 − Create ... Read More
Swift provides an hasPrefix() function to check if a string starts with a specified substring. The hasPrefix() function returns a boolean value which indicates whether the specified substring matches the starting string characters of the input string. The hasPrefix() function is case sensitive, which means according to this function “a”, and “A” are two different values. Input String = “Ram got first place” SubString = “Ram” Output Yes Here, the characters of the substring match the starting characters of the input string.

Swift provides an hasSuffix() function to check a string end with a specified substring. The hasSuffix() function returns a boolean value which indicates whether the specified substring matches the ending characters of the input string. The hasSuffix() function is case sensitive that means according to this function “t”, and “T” are two different values. Input String = “Today is cloudy day” SubString = “day” Output yes Here, the character of the substring matches the ending characters of the input string. Syntax func hasSuffix(value) Here, the value represents a string. This function returns true if the value matches ... Read More
In Swift, a dictionary is an unordered collection in which data is stored in the form of key-value pairs. To add elements to a dictionary we can use any of the following methods − Using Bracket notation Using updateValue() method Method 1: Using Brackets Notation We can key-value pairs in the dictionary using bracket notation or we can say that using subscript notation. In this method, we can add a new key in the brackets and assign the corresponding value. If the specified key already exists, then it will replace the value of that key we the new ... Read More
An array is a collection of elements of homogeneous datatypes stored in contiguous memory locations. Python does not provide support for the built-in arrays. If you need to work with arrays you need to import the "array" module or, use the arrays in numpy library.We can use lists instead of arrays in Python. However, we cannot restrict the elements of a list to be of the same data type. The given task is to remove all the occurrences of an element in an array/list. i, e. we to remove the specified element including the duplicate elements. Let us understand how this ... Read More
