Write a function named count_vowels that accepts a string as an argument. The function should count the number of times each vowel (the letters a, e, i, o, and u) appears in the string, and store those counts in a dictionary. When the function ends, the dictionary should have exactly 5 elements. In each element, the key will be a vowel (lowercase) and the value will be the number of times the vowel appears in the string.

hi I really need help with this assignment problem flip_matrix(mat:list)->list You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix:W R I T XH D R L GL K F M VG I S T CW N M N FExpected:W N M N FG I S T CL K F M VH D R L GW R I T X Matrix:L CS PExpected:S PL C Matrix:A D JA Q HJ C IExpected:J C IA Q HA D J
Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…
1c) Average sentence length We will create a function (avg_sentence_len) to calculate the average sentence length across a piece of text. This function should take text as an input parameter. Within this function: sentences: Use the split() string method to split the input text at every '.'. This will split the text into a list of sentences. Store this in the variable sentences. To keep things simple, we will consider every "." as a sentence separator. (This decision could lead to misleading answers. For example, "Hello Dr. Jacob." is actually a single sentence, but our function will consider this 2 separate sentences). words: Use the split() method to split the input text into a list of separate words, storing this in words. Again, to limit complexity, we will assume that all words are separated by a single space (" "). (So, while "I am going.to see you later" actually has 7 words, since there is no space after the ".", so we will assume the this to contain 6 separate words in our…
