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).
