PTA Search 250 (10 points)

Topic restatement

Find 250 (10 points)

The other party didn't want to talk to you, and threw a string of numbers at you... And you must find the tall moving number "250" from this string of numbers.

Input format:

Enter the number of integers whose absolute value does not exceed 1000 in one line, and it is guaranteed that there is at least one "250".

Output format:

The first occurrence of "250" in a line is the first number thrown by the other party (counting starts at 1). The question guarantees that the output number is within the integer range.

Input sample:

888 666 123 -233 250 13 250 -222

Sample output:

5
