The answer is c because all you are doing here is subbing the variable r for 5b.
B is one.
A < C and D are rational
Im thinking about E. It looks like a recurring decimal at first sight but I think its irrational.
Assuming we need to find i such that
1 ≤ i ≤ n and t[i]=i.
If we need to find only the first occurrence, we can do:
for i:1 to n {
if t[i]=i then return(i)
}
If exhaustive search is required, then put the results (values of i) in an array or a linked list, return the number of values found, and the array (or linked list).
