IBM Cognos Report Studio & Algorithms Quiz

Repeated squaring (exponentiation by squaring) computes n^1000 by decomposing the exponent into binary. 1000 in binary is 1111101000 (base-2), which has 10 bits requiring 9 squarings, and Hamming weight of 6 ones requiring 5 extra multiplications. Total: 9 + 5 = 14 multiplications. This is dramatically fewer than 1000 for naive multiplication.

When the maximum value k in the list is known, we can use counting sort which runs in O(n+k) time - O(n) to count occurrences and O(k) to output sorted values. This is better than comparison-based sorts like merge/quick sort which require O(n log n) in the best case.

Reversing a linked list requires traversing the list once and redirecting each node's next pointer to its predecessor. This is done in a single pass with constant work per node, giving O(n) time complexity.

Cognos 8 uses a web-based architecture that requires only a browser on the client side, making it a zero footprint architecture with no client software installation needed.

In Cognos Report Studio, the Insertable Objects pane contains three tabs: Source (for data sources), Data Items (for available query items), and Toolbox (for report elements). The Properties tab is part of a different pane.

Cognos Report Studio's Explorer Bar contains three explorers: Page Explorer (for report pages), Query Explorer (for data queries), and Condition Explorer (for conditional formatting/logic). There is no Work Area Explorer.

Drill-through reports in Cognos allow users to navigate from a summary report to a detailed report by clicking on data points, such as values in a chart. This is the primary purpose of drill-through functionality.

In dimensional modeling, a slicer is a dimensional filter that reduces the scope of data included in measure calculations (rollups) while keeping the dimension visible in the report. Regular filters remove rows entirely.

Cognos Report Studio supports multiple output formats including Excel, XML, and HTML, along with PDF and CSV. Word format is not a standard export option in Report Studio.

A Page in Report Studio is composed of three main sections: the Page Header (appears at the top), the Page Body (contains the main report content), and the Page Footer (appears at the bottom). A 'Page sub-header' is not a standard component of a page structure.

Report Studio supports creating List, Map, and Repeater reports. A 'View' is not a type of report in Report Studio - it is a database object or a different concept altogether, making it the correct answer for what is NOT a report type.

Report Studio supports interactive analysis features: Drill Up (navigate to higher-level data), Drill Through (link to related reports), and Drill Down (access detailed data). 'Drill Back' is not a standard navigation feature in Report Studio.

A Text Box Prompt is specifically designed to retrieve data based on an exact value that users type, such as a name, account number, or ID. Value Prompt typically presents a dropdown list, Date Prompt is for calendar selection, and Generate Prompt is not a standard prompt type.

This minimum path sum problem can be solved by recursion (exponential O(2^n) by exploring all paths) or optimally by dynamic programming (O(n^2) using memoization). Brute force would be O(n^3) or worse, and divide & conquer doesn't apply to this DP structure.

This is the same minimum path sum problem - recursion explores all possible paths giving O(2^n) complexity, while dynamic programming with memoization achieves O(n^2) by avoiding recomputation. Divide & conquer is not applicable to this DP-optimized structure.

IBM Cognos Framework Manager is a metadata modeling tool used to create and manage data models for Business Intelligence reports. It defines the relationships between data sources, creates calculated columns, and builds the semantic layer that Report Studio uses. It is not an ETL tool (those extract/transform/load data), not a database, and not a web portal.

The Insertable Objects pane in IBM Cognos Report Studio has multiple tabs. The Source tab provides access to available data sources. The Toolbox tab contains report objects like lists, crosstabs, and charts. The Data Items tab shows available data items from the query. The Properties tab (B) is a separate floating window, not a tab within the Insertable Objects pane.

In IBM Cognos Report Studio, a Date Prompt is specifically designed for date selection and can be configured to accept single dates or date ranges (between two dates). Tree Prompts handle hierarchical data selection. Value Prompts are for single value selection. Interval prompts aren't a standard Cognos prompt type for this purpose.
