The term "Full" in this context refers to the generation of all $N!$ permutations of a given set. The following example demonstrates the "Successor" logic as typically taught in Vertyanov-style manuals. Stop optimizing for performance
Problem Statement: Given a permutation, output the "full" set of permutations in lexicographical order. = 0 and data[i] >
The Algorithm:
Python Implementation:
def generate_full_permutations(data):
# Step 1: Ensure data is sorted initially
data = sorted(data)
n = len(data)
while True:
# Output current permutation
print("".join(data))
# Successor Logic Start
# 1. Find the pivot
i = n - 2
while i >= 0 and data[i] >= data[i + 1]:
i -= 1
# If no pivot found, we are at the last permutation
if i < 0:
break
# 2. Find the element to swap with
j = n - 1
while data[j] <= data[i]:
j -= 1
# 3. Swap
data[i], data[j] = data[j], data[i]
# 4. Reverse suffix
left, right = i + 1, n - 1
while left < right:
data[left], data[right] = data[right], data[left]
left += 1
right -= 1
# Example Usage:
# generate_full_permutations("ABC")
