How to find repeating sequence of characters in a given array?

Question

My problem is to find the repeating sequence of characters in the given array. simply, to identify the pattern in which the characters are appearing.

Answer 1

Put all your character in an array e.x. a[]

i=0; j=0;
for( 0 < i < count ) 
{
if (a[i] == a[i+j+1])
    {++i;}
else
    {++j;i=0;}
}

Then the ratio of (i/j) = repeat count in your array. You must pay attention to limits of i and j, but it is the simple solution.
