You say to compare Y and Z in each iteration? Z is always greater than Y, so what do you mean by comparing?

In the instruction is said: Each part of the string is of the form: h|m|s where h, m, s (h for hour, m for minutes, s for seconds) are positive or null integer (represented as strings) with one or two digits. There are no traps in this format.

Here are strings that I am getting for attemps:
Log
01|15|59, 1|47|16, 01|17|20, 1|32|34, 2|17|1702|15|59, 2|47|16, 02|17|20, 2|32|34, 2|17|17, 2|22|00, 2|31|4102|15|59, 2|47|16, 02|17|20, 2|32|34, 2|32|34, 2|17|17

Can anyone says what are 2|17|1702|15|59, and 2|31|4102|15|59,? These are not in order and causing wrong results.

Thanks!

How can you check if an element is peak-plateau? any role ?
Cheers

it is correct, I meant in the follwing vector <1, 2, 2, 2, 1> how should I find the peak-plateau?

thanks
