Question

JAVA - take each for loop and rewrite as a while statement

a) int result = 0;

for (int i = 1; i <= 10; i++) { result = result + i;} System.out.println(result);

b) int result = 1;

for (int i = 1; i <= 10; i++) {result = i - result;} System.out.println(result);

c) int result = 1;

for (int i = 5; i > 0; i--) {result = result * i;} System.out.println(result);

d) int result = 1;

for (int i = 1; i <= 10; i = i * 2) {result = result * i;} System.out.println(result);
