Question 1
Regression testing is primarily related to
- Functional testing
- Development testing
- Data flow testing
- Maintenance testing
Correct one Blow There . So, option (A) is correct.
Question 2
Of the following sort algorithms, which has execution time that is least dependent on initial ordering of the input ?
Option
- Insertion sort
- Quick sort
- Merge sort
- Selection sort
So, option (C) is correct.
Question 3
The following circuit compares two 2-bit binary numbers, X and Y represented by X1X0 and Y1Y0 respectively. (X0 and Y0 represent Least Significant Bits)
Under what condition Z will be 1 ?
- X > Y
- X < Y
- X = Y
- X != Y
Given, expression is,
Z = X1Y1′ + (X1⊙Y1)X0Y0′
Therefore, if X > Y, then Z is 1. Option (A) is correct.
