Solution for Triangle Problem

# you can write to stdout for debugging purposes, e.g.
# print("this is a debug message")
def check_triangle(numbs):
    total = sum(numbs)
    for i in range(3):
        item = numbs[i]
        two_sum = total - item
        if item >= two_sum:
            return False
    return True

    # 1, 2, 3, 4, 5, 6
    if len(A) < 3:
        return 0
    
    A = sorted(A)
    for i in range(len(A)-2):
        if check_triangle(A[i:i+3]):
            return 1
    return 0
