QuestionHint and solution stay closed until you open them
The first line is n. The second line has n integers. The third line is a target.
Print the 0-based index of the first time the target appears, or -1 if it is missing.
Input. Line 1: n. Line 2: n integers. Line 3: target.
Output. One integer: the index, or -1.
Constraints
- 1 ≤ n ≤ 1000
Examples
Input

Output
2
Input
4 1 2 3 4 9
Output
-1
Hint
- A for-loop with enumerate finds the first hit.
- list.index(target) raises if missing — catch it, or scan by hand.
