1. Write a program, which finds a subsequence of numbers with maximal sum. E.g.: {2, 3, -6, -1, 2, -1, 6, 4, -8, 8} à 11
2. Write a program, which finds the most frequently occurring element in an array. Example: {4, 1, 1, 4, 2, 3, 4, 4, 1, 2, 4, 9, 3} à 4 (5 times). 11. Write a program to find a sequence of neighbor numbers in an array, which has a sum of certain number S. Example: {4, 3, 1, 4, 2, 5, 8}, S=11 à {4, 2, 5}.
