Fixed following SonarQube issues:

1. Boolean checks should not be inverted.
2. The comma operator should not be used.
3. Arguments to built-in functions should match documented types.
4. Redundant pairs of parentheses should be removed.
5. A conditionally executed single line should be denoted by indentation, 
6. A while loop should be used instead of a 'for' loop.
