Algorithm that returns highest amplitude .Can someone help

A planet with 4 seasons: winter, spring, summer and autumn. A year has N days and every season lasts for exactly N/4 days. The year starts on the first day of winter and ends on the last day of autumn. How do I display amplitude with highest temperatures("AUTUMN). An array T of N integers denoting the temperatures on all days of the year. given array T? Given T=[2,-3,3,1,10,8,2,5,13,-5,3,-18]: (1 -3 3)WINTER (1 10 8)SPRING (2 5 13)SUMMER (-5 3 -18)AUTUMN
