Code Issue

For question no 16.c of arrays there is a minor issue in Method 3

int findEquilibriumIndex(int a[],int n){
	int i = 0,j;
	int sum = 0, sumLeft = 0;

	for(i=0; i<n; i++){
		sum += a[i];
	}
	for(j=0;j<n;j++){
		sum = sum - a[j];
		**sumLeft += a[j];** //Should have come after if condition
		if(sum == sumLeft){
			return j;
		}
	}
	return 0;
}
