Exercise 1.28 You are asked to write a C program to concatenate the binary formats of two given non-negative integers and output the result in decimal format. Input The input consists of the number of test cases, m, in the first line and followed by m test cases. Each test case consists of two non-negative integers in the range between 0 and 216-1, both inclusively. An example is as follows, 3 10 5 62 70 Output The output should be m lines of integer values. Each line should be the decimal format of the corresponding concatenation result. 85 26 7

Exhibit what we mean by coding norms.

Please explain Why do computer scientists typically rely on ’worse-case’ analysis? Group of answer choices   a. It allows us to be more conservative and when using the upper-bounds in terms of time complexity. This is a 'safer' way for us to determine if the performance is fast enough.   b. No other analysis exist or have been invented yet.   c. Most of the famous computer scientists use worse-case analysis, so every one just copies what they have done previously.
