How to optimise the time limit in the code?

SUbmission status : Time limit exceed

#include <stdio.h>
#include <stdbool.h>

bool maxPresent(long int arr[],long n,long max);

int main()
{
int t;
scanf("%d",&t);
while(t–)
{
long int n,sweetValue[100000],counter=0;
scanf("%ld",&n);
long max=0;
for(long int i=0;i<n;i++)
{
scanf("%ld",&sweetValue[i]);
if(sweetValue[i]>max)
max=sweetValue[i];
}

    bool canShift = maxPresent(sweetValue,n,max);

    if(canShift==true)
    {
        long int tempArray[100000]; //assigning last value to the first index...
        for(int i=0;i<n/2;i++)      //assigning rest of the value to the tempArray...
        {
            tempArray[0]=sweetValue[n-1];
            for(int j=1;j<n;j++)
            {
                tempArray[j] = sweetValue[j-1];
            }
            canShift = maxPresent(tempArray,n,max);  //check after shit !st half has tha max value or not
            if(canShift==true)
                continue;
            else
                counter++;
        }

    }
    printf("%ld\n",counter);



}
return 0;

}

bool maxPresent(long int arr[],long n,long max)

bool flag=false;
for(int i=0;i<n/2;i++)
