Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

The base Output variable result is set to a default
value of -404 which can be modified. Additionall
y, you can add or remove these output variables.
Input Format
The first line contains an integer N denoting the
size of the string.
The second line contains the input string S.
Sample Input

Constraints
1 <= N <= 5
"a" <= S[i] <= "z" for every i from 0 <=i< N.
Output Format
Return a single integer denoting the total sum of
all the powers of every unique alphabet present i
n the string.
Sample Output
Explanation
The unique alphabets present in the string are
"a" and "c" with frequencies 3 and 2 respectively.
The power of "a" is its position in the alphabet
(1) raised to its occurrence (3). hence the power
of a = 13 = 1.
Similarly, the power of "c" is its position in the al
phabet (3) raised to its occurrence (2). hence the
power of "c" = 32 = 9.
Therefore, total power = power of a - power o
fc' = 9 + 1 = 10.
Hence, the output is 10.

Q1. Strings: Power of the string
Given string S contains lowercase alphabets.
The power of an alphabet is defined as the positi
on of the alphabet( i.e. A - 1, B - 2, C-3, D-4, E
5, F-6 and so on...) raised to the number of ti
mes the alphabet occurs in the given string.
Calculate the sum for the power of every unique
alphabet present in the string.
There will be multiple test cases running so the I
nput and Output should match exactly as provid
ed.
The base Output variable result is set to a default
value of -404 which can be modified. Additionall
y, you can add or remove these output variables.
Input Format
The first line contains an integer N denoting the
size of the string.
The second line contains the input string S.
