Which of the following problems CANNOT be effectively solved using bit manipulation techniques similar to UTF-8 validation?

easy🔍 Pattern Recognition Q2 of Q15

Bit Manipulation - UTF-8 Validation

AChecking if a sequence of bytes follows a specific bit pattern encoding

BParsing nested parentheses in a string to check balanced pairs

CCounting the number of set bits in an integer

DValidating continuation bytes in multi-byte character encodings

Step-by-Step Solution

Solution:

Step 1: Analyze problem types
Bit manipulation excels at checking bit patterns and counting bits but is not suited for parsing nested structures.
Step 2: Identify problem requiring stack or recursion
Parsing nested parentheses requires stack-based parsing, not bit-level checks.
Final Answer:
Option B -> Option B
Quick Check:
Balanced parentheses need stack, not bitmasking [OK]

Quick Trick: Bit manipulation can't parse nested structures [OK]

Common Mistakes:

MISTAKES

Trap Explanation:

PITFALL

Candidates often overgeneralize bit manipulation to parsing problems requiring stacks.

Interviewer Note:

CONTEXT

Checks candidate's understanding of bit manipulation limits versus parsing needs.
