Find largest d in array such that a + b + c = d | function to find largest d.
sort the array in ascending order.
iterating from backwards to find the required largest d.
since all four a , b , c , d should be distinct.
if the current combination of j , k , l in the set is equal to S [ i ] return this value as this would be the largest d since we are iterating in descending order.
