#### Determining if a pair of integers in a list sums to a target value

This problem asks whether a given list of integers contains a pair of numbers whose sum equals a given target value. For example, if the list is [1, 2, 3, 4, 5] and the target value is 6, the answer would be True (1 + 5 = 6).

#### Problem

```Given a list of integers and a target value, determine if there is a pair of integers in the list that sum to the target value.
Example input: [1, 2, 3, 4, 5], target=6
Example output: True (1 + 5 = 6)```

```def sum_to_target(lst, target):

This function takes a list of integers and a target value and returns True if there is a pair of integers in the list that sum to the target value.

# Create a set of the list
s = set(lst)
# Iterate through the list
for i in lst:
# If the target minus the current value is in the set, return True
if target - i in s:
return True
# If the target minus the current value is not in the set, return False
return False

# Test cases
print(sum_to_target([1, 2, 3, 4, 5], 6))
print(sum_to_target([1, 2, 3, 4, 5], 7))
print(sum_to_target([1, 2, 3, 4, 5], 8))
print(sum_to_target([1, 2, 3, 4, 5], 9))
print(sum_to_target([1, 2, 3, 4, 5], 10))
print( sum_to_target([1, 2, 3, 4, 5], 11))
print(sum_to_target([1, 2, 3, 4, 5], 12))
print(sum_to_target([1, 2, 3, 4, 5], 13))
print(sum_to_target([1, 2, 3, 4, 5], 14))
print(sum_to_target([1, 2, 3, 4, 5], 15))

This solution is optimal because it only iterates through the list once and uses a set to check if the target minus the current value is in the set.
