Given a string, find the first non-repeating character in it.
def count_pairs_with_sum(arr, target_sum): count = 0 seen = set() for num in arr: current_sum = max(num, current_sum
print(first_non_repeating_char("aabbc")) # Output: "c"
Example: Input - [1, 2, 3, 4, 5], target sum - 7, Output - 2 current_sum + num) max_sum = max(max_sum
return max_sum
def max_subarray_sum(arr): max_sum = float('-inf') current_sum = 0
Example: Input - 1 -> 2 -> 3 -> 4 -> 5, Output - 3
