Complexity Analysis
Calculate the total sum of the array.
Check if the total sum is divisible by 3. If not, return
false
.
Set the target sum as the total sum divided by 3.
Initialize a running sum and a counter for the number of parts found.
Iterate through the array, adding each element to the running sum.
If the running sum equals the target sum, reset the running sum to 0 and increment the counter.
If the counter reaches 2 before the end of the array, return
true
.
If the end of the array is reached without the counter reaching 2, return
false
.
