Find min K

Given a array, find the min K which means the count of number to delete that will make the last number

#include<stdlib.h>
int findMinK(int* array, int len){
	int i = len-1;
	int j;
	int k =len;
	int tempK =0;
	int temp = 0;
	for(; i >= 0; i--){
		temp = array[i];
		tempK = len-1 -i;
		for(j = 0; j < i; j++){
			if(array[j] < temp){
				tempK++;
			}
		}
		if(k > tempK){
			k = tempK;			
		}
	}
	return k;
}

int main(){
	int array[] = {3,2,5,6,7};
	int result = findMinK(array, 5);
	printf("The min K is: %d",result);
	getchar();
}

 as the min number.
