Given an array, check if there exist 2 elements of the array such that their sum is equal to the sum of the remaining elements of the array.
Question
Given an array, check if there exist 2 elements of the array such that their sum is equal to the sum of the remaining elements of the array.
Solution
Sure, here is a Python solution for the problem:
def check_sum(arr):
# Calculate the total sum of the array
total_sum = sum(arr)
# Create a set to store the elements of the array
elements = set()
for num in arr:
# Calculate the target sum
target_sum = total_sum - num
# If the target sum is divisible by 2, it means there might be two elements whose sum is equal to the sum of the remaining elements
if target_sum % 2 == 0:
target_sum //= 2
# If the target sum is in theSimilar Questions
