A complete bracelet is an array with at least one subsequence (pattern) repeating at least two times, and completely - the subsequence cannot be cut-off at any point. The subsequence must have length two or greater.

Complete bracelets:

{ 1, 2, 3, 3, 1, 2, 3, 3 }  // Pattern: { 1, 2, 3, 3 }

{ 1, 2, 1, 2, 1, 2, 1, 2 }  // Pattern: { 1, 2 } or { 1, 2, 1, 2 }

{ 1, 1, 6, 1, 1, 7, 1, 1, 6, 1, 1, 7, 1, 1, 6, 1, 1, 7 }  // Pattern: { 1, 1, 6, 1, 1, 7 }

{ 4, 4, 3, 4, 4, 4, 4, 3, 4, 4 }  // Pattern: { 4, 4, 3, 4, 4 }

Incomplete bracelets:

{ 1, 2, 2, 2, 1, 2, 2, 2, 1 }  # Incomplete (chopped off)

{ 1, 1, 6, 1, 1, 7 }  # Incomplete (subsequence repeats only once)

Create a function that returns true if a bracelet is complete, and false otherwise.

Examples

CompleteBracelet({ 1, 2, 2, 1, 2, 2 }) ➞ true

CompleteBracelet({ 5, 1, 2, 2 }) ➞ false

CompleteBracelet({ 5, 5, 5 }) ➞ false
// potential pattern { 5, 5 } cut-off (patterns >= 2)

Notes

• Patterns must be at least two integers in length.
• Use Comments for a hint if you are stuck.
