BIG-O / THETA ORDER
1 < log n < (log n)² < n < n log n < n² < n²log n < n³ < 2ⁿ
Θ = tight bound/actual growth, O = upper bound/worst-case, Ω = lower bound. Ignore constants + smaller terms. Example: 3n²+5n+1 = Θ(n²)

LOOP RULES
i++ → O(n)
i=i+2 → O(n)
i=i*2 or i=i/2 → O(log n)
Nested loops multiply, sequential loops add.
Nested: for(){while(){}} → O(n log n)
Sequential: for(){} while(){} → O(n)+O(log n)=O(n)

UNIVERSAL LOOP ANSWER
“Outer loop runs ___ times. Inner...

Software Testing

1)Explain testing principles in detail.

Software testing follows certain fundamental principles that help improve the effectiveness of testing.

1) Testing shows presence of defects

Testing can reveal defects (bugs) in the software.

Example: Even after testing, some hidden bugs may remain.

2) Exhaustive testing is impossible It is not possible to test all inputs, conditions, and paths.Testing is done on selected test cases.

3) Early testing - Testing should start as early as possible in the development
