[solved] – Question 8510
write a java application to calculate the exponent value of a number using the following specifications:
.prompt the user to enter an interger value
.pass the interger value to the method square, which squares the number and to a method cubes the number. The result must be returned to the main method.
The main method must print the results along with a suitable message

[solved] – Question 85137
Write a program that computes the results of integer and floating-point division, where variables a, and b are declared as integers, c and d are declared as floating-point numbers, and all are user-specified.
Integer division is defined as whole-number division. For example, 1/2 (as integers) = 0. Whereas, if we specified 1/2 (as “floats”; i.e., floating-point numbers), the result is 0.5. In C++, the result of an arithmetic operation (e.g., whether the computer computes the result as an integer or as a float) is specified by the data type.
Your task is to make edits within main such that, when run, the program produces the following console output:
Enter two integers: [user-specified value for a] [user-specified value for b]
Integer division: [a]/[b] = [a]/[b]
Floating-point division: [c]/[d] = [c]/[d]
Mixed-type division: [a]/[d] = [a]/[d]
Mixed-type division: [c]/[b] = [c]/[b]

[solved] – Question 85157
Write a function matched(s) that takes as input a string s and checks if the brackets “(” and “)” in s are matched: that is, every “(” has a matching “)” after it and every “)” has a matching “(” before it. Your function should ignore all other symbols that appear in s. Your function should return True if s has matched brackets and False if it does not.
Hint: Keep track of the nesting depth of brackets. Initially the depth is 0. The depth increases with each opening bracket and decreases with each closing bracket. What are the constraints on the value of the nesting depth for all brackets to be matched?
Here are some examples to show how your function should work.
>>> matched(“zb%78”)
True
>>> matched(“(7)(a”)
False
>>> matched(“a)*(?”)
False
>>> matched(“((jkl)78(A)&l(8(dd(FJI:),):)?)”)
True
