3a. Write a program that reads a social security number wriben as contiguous
digits (for instance, 509435456), uses the charAt method to obtain
each character and then prints each digit on a separate line followed by a
colon and the digit printed the number of times equal to its value. Thus the
output for 509435456 would be
5:55555 0: 9:999999999 4:4444 3:333 5:55555 4:4444 5:55555 6:666666
Hint: Use a char variable, e.g., index, for the inner loop
control variable and write the inner for loop as for(char index = '1';
index <= digit; index++) where digit is the char
variable use to store the digit taken from the string.
3b. Write the program so that index is an int variable. This means you must convert the character assigned to digit to an int.
Use FEB 2 Prog3 for converting a char to a digit; FEB 6 Prog1 for a char driving a loop; Prog6 FEB 2 for nested loop.
