Design a program that asks the user to enter a string containing a series of single digit numbers with nothing separating them.

Design a program that asks the user to enter a string containing a series of single

digit numbers with nothing separating them. The program should display the sum

of all the single digit numbers in the string. For example, if the user enters 2514,

the method should return 12, which is the sum of 2, 5, 1, and 4. (Hint: The

stringToInteger library function can be used to convert a single character to an

integer.) - pseudocode
