Problem 2:
Max Subsequence sum using 3 nested for loops. (n^3)
Max subsequence sum using 2 nested for loops. <-- Challenge (n^2)
You shold print the sequence.
Problem 3:
You are given a sequence of characters, you must check if this sequence of characters form a palindrome.
Example:
n=5
a b c b a
ANSWER: YES
Example 2:
n=5
a b c d e
ANSWER: NO
Problem 4:
Given a sequence of characters followed by a pattern.
You shold check if this pattern exists in the sequence of characters.
Example:
n=5
a b c d e f
n=3 (pattern)
b c d
ANSWER: YES
Problem 5: (Bonues)
Given two arrays a[] and b[] where a[0] and b[0] correspond to a and b of line 0 where y=ax+b and so on (a[1] and b[1] corresponds to line 1)
You are required to check if there existss three lines intersecting at the same point.
Example:
n=5
1 1 1 1 1 //array a (slopes)
2 3 5 6 7 //array b (y-intercept)
