Problem Statement: The program takes a string and creates a dictionary with key as first character and value as the count of letter in the string and also, sort the dictionary w.r.t the values of count in descending order or sort it based on the key in alphabetical order. Pseudocode: Start of build_dict function An empty dictionary is declared Start of for loop to traverse through the letters of the string If letter is not present as a key in the dictionary The letter is initialized as the key and assign 1 to it ( since initially the count would be 1) Else The value of the letter as key in the dictionary is increased by 1 End of build_dict function Sort the dictionary and assign it back to the same dictionary variable Start of print_dict function Iterate over all the items of the dictionary Print the key and value End of print_dict function Start of main function User must enter a large string and store it in a variable Call the build_dict function with string parameter and return the dictionary Print dictionary using print_dict function End of main function Hint:- You can also use sorted function to sort the dictionary with respect to the values associated with keys in descending order.

Dictionary-Returned Functiona) Define a function, dictSqrt() with a parameter, x: 1) Create a list, num and uses a loop to store, x numbers into the list in the range of (0, x). 2) Create a list, sqrtNum and store all sqrt of the numbers saved in the list above. 3) Use dict() and zip() to create a dictionary, sqrtDict, as the return value with numbers as the keys and their corresponding sqrt as the values.b) Define a main() function to do the following: 1) Get a random integer, n, in the range (1, 10).2) Call dictSqrt() with the argument and print the returned dictionary.c) Call main() function to initiate the tasks to be performed. Example OutputdictSqrt(3)will print the following:{0:0, 1:1, 2:1} PYTHON
PYTHON!!!! Write a function that takes two dictionaries as arguments and merges them into a new dictionary and returns this new dictionary. If the same key exists in both dictionaries, then the larger value is stored as the value of the key in the new dictionary. You can assume that all values are comparable. """ def mergeDicts(dict1, dict2):
void dict_clear (dict_t* dict); This function clears the dictionary dict, destroying each pair key/value, but does not destroy dict itself (remember that dict was allocated using dict_create, so it will need to be freed at some point, but this is not this function’s job.) This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash). This simple function returns the current size of the dictionary: size_t dict_size (const dict_t* dict);
