Algorithm FindThreeOccurrences(A, n, x)
Input: Array A of integers, integer n (size of A, n ≥ 3), integer x
Output: Boolean value (True if exactly 3 occurrences of x, False otherwise)
// Step 1: Initialize a counter
count - 0
// Step 2: Traverse the array to count occurrences of x
for i - 0 to n-1 do
if A[i] = x then
count - count + 1
end if
// Step 3: Early exit if count exceeds 3
if count > 3 then
return False
end if
end for
// Step 4: Check if count is exactly 3
if count = 3 then
return True
else
return False
end if
end Algorithm
