Analyse the given program segment and answer the following questions: for(int i = 3; i <= 4; i++) { for(int j = 2; j < i; j++) { System.out.print(""); } System.out.println("WIN"); } (i) How many times does the inner loop execute? (ii) Write the output of the program segment.

Answer
Exam answer
(i) 3 times (ii) WIN WIN
Explanation
(i) Count the inner loop pass by pass, since its limit depends on i: when i = 3, j runs 2 only — 1 time when i = 4, j runs 2 and 3 — 2 times total = 3 times Whenever an inner loop is bounded by the outer variable, you must add the passes rather than multiply. (ii) The inner loop prints "" — an EMPTY string, which shows nothing at all. Only the println("WIN") produces visible output, and the outer loop runs twice, so the output is WIN twice on separate lines.

Example: n = 246
sum = 2 x 2 + 4 x 4 + 6 x 6 = 56
56 is an even number as well as last digit is 6 for both sum as well as the number.2026
