Problem: If the price of a product increases by 20% and then decreases by 15%, what is the net percentage change?
Solution: Let original price = ₹100 After 20% increase: ₹100 + 20% = ₹120 After 15% decrease: ₹120 - 15% of ₹120 = ₹120 - ₹18 = ₹102 Net change = ₹102 - ₹100 = ₹2 Net percentage = (2/100) × 100 = 2% increase
Answer: 2% increase

Solution (Java):
public class ReverseString { public static String reverse(String str) { char[] chars = str.toCharArray(); int left = 0, right = chars.length - 1; while (left < right) { char temp = chars[left]; chars[left] = chars[right]; chars[right] = temp; left++; right--; } return new String(chars); }
public static void main(String[] args) { String str = "HCL"; System.out.println(reverse(str)); // Output: LCH }}Time Complexity: O(n) Space Complexity: O(n)
