What will be the output of the following code snippet?for (int i = 1; ...
Code Explanation
The given code snippet consists of nested loops that output specific values based on the loop indices.
Outer Loop
- The outer loop iterates with `i` taking values from 1 to 3.
- For each value of `i`, the inner loop executes.
Inner Loop
- The inner loop iterates with `j` from 1 to the current value of `i`.
- The inner loop prints the current value of `i` followed by a space.
Iteration Breakdown
- When i = 1:
- The inner loop runs for `j = 1`.
- Output: `1 ` (printed once)
- When i = 2:
- The inner loop runs for `j = 1` and `j = 2`.
- Output: `2 ` (printed twice)
- When i = 3:
- The inner loop runs for `j = 1`, `j = 2`, and `j = 3`.
- Output: `3 ` (printed three times)
Final Output Compilation
Combining all the outputs from each iteration:
- From `i = 1`: `1 `
- From `i = 2`: `2 2 `
- From `i = 3`: `3 3 3 `
Thus, the final printed output is: `1 2 2 3 3 3 `
Conclusion
The correct answer is option 'A': 1 2 2 3 3 3, as it accurately reflects the output of the nested loops in the code snippet.

What will be the output of the following code snippet?for (int i = 1; ...
The outer for loop iterates over the values of i from 1 to 3. The inner for loop iterates over the values of j from 1 to i. In each iteration, the value of i is printed. The loop prints the values 1, 1, 2, 1, 2, and 3.
