c - finding the minimum element in a cyclic sorted array -


this question has answer here:

i have tried following code find out minimum element in cyclic sorted array. fails when low = 1 , high =2 because mid 1 , a[mid]=a[1] greater a[high].

i trying use binary search here find solution.

//finding minim element in cyclic sorted array int arrc[]={10,13,1,3,4,5,8}; int low=0,high =6; int mid=0,reset =1; while (low < high) {     mid = (low+ high)/2;     if (arrc[mid]>arrc[high])     {         low = mid;     }     else if (arrc[mid] < arrc[high])     {         high = mid;      } } printf("minimum element %d",arrc[mid+1]);

use normal binary search, if arrc[high] < arrc[low], treat arrc[high] infinity account wrap around. change line:

if (arrc[mid]>arrc[high])

to:

if (arrc[high] < arrc[low] || arrc[mid] > arrc[high])
