Given an array temps of double, containing temperature data, and an int variable n that contains the number of elements in temps: Compute the average temperature and store it in a variable called avgTemp. Besides temps, n, and avgTemp, you may use only two other variables -- an int variable k and a double variable total, which have been declared.

- Make an array with dtype = uint8 and elements of your choosing. Keep adding to it until (one of) the items go over 255. What happens? Hint: make an array, and just add a constant to it.

Declare any additional variables as necessary.arrow_forwardYou are given an array-like data structure Listy which lacks a size method. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers, find the index at which an element x occurs. If x occurs multiple times, you may return any index. Write code with explanationarrow_forward
- The bank will store a record for each account consisting of a customer number (an integer) representing the owner of the account, an account type (a single char: C for chequing, S for savings, and M for mutual fund), and the balance of the account (a double). These are kept in three arrays-an array of customer numbers, an array of types, and an array of balances. A sample of what this might look like appears below: Customer Array 102241 992944 992944 Type Array C S C Balance Array 1.29 22.50 1.24 The entries in the array correspond to one another-for example, the first slot in all three arrays represent the fact that customer number 102241 has a chequing account with $1.29 in it. As is shown, the same customer number can appear several times, as customers can have more than one account. These are called parallel arrays, because the slots in each correspond, and the really important thing about parallel arrays is that if you shuffle around anything in one array, you have to…arrow_forwardThe bank will store a record for each account consisting of a customer number (an integer) representing the owner of the account, an account type (a single char: C for chequing, S for savings, and M for mutual fund), and the balance of the account (a double).

For example, if the array contains ['C', 'p', 't', 'S', ',', '1', '2', '1', '.', 'i', 's', 'f', 'u', 'n', '!'], then the function should remove the punctuation characters. The function must remove the characters by shifting all characters to the right of each punctuation character, left by one spot in the array. This will overwrite the punctuation characters, resulting in: ['C', 'p', 't', 'S', '1', '2', '1', 'i', 's', 'f', 'u', 'n']. In this case, the function returns 3. Note: if the array does not contain any punctuation characters, then the array is unchanged and the function returns 0.arrow_forward
