multiply b by zero

thank you

please help me to solve this question

Determine 20 patterns and texts which will result in the worst case performance and create a scattergraph of
CPU execution time plotted against length(text)*length(pattern). The product, length(text)*length(pattern),
should be approximately equal to, 102, 104, 106, 108 and 1010, and for each product you should construct 4
pattern-text examples. As a guide you should ¯nd that the worst case execution time for a product length
of 1010 is over 10 seconds. The total ¯le size should be no more than 100MBytes. Note: you will need to
write a simple c program to generate the text and pattern ¯les.

We can use Bitwise complement operator

int a=15,b=10;

pf("%d", a+(~b+1));
