Question: 1 . Write a recursive method named moveToEnd that accepts a string s and a character c as parameters, and returns a new string similar

1 .

Write a recursive method named moveToEnd that accepts a string s and a character c as parameters, and returns a new string similar to s but with all instances of c moved to the end of the string. The relative order of the other characters should be unchanged from their order in the original string s

.

If the character is a letter of the alphabet, all occurrences of that letter in either upper or lowercase should be moved to the end and converted to uppercase. If s does not contain c

,

it should be returned unmodified.

2 .

Write a recursive method named power that accepts two integers representing a base and an exponent and returns the base raised to that exponent. For example, the call of power

(3, 4)

should return

34

81 .

If the exponent passed is negative, throw an IllegalArgumentException.
