```function minNumberInRotateArray(rotateArray)
{
    let [left , right] = [0 , rotateArray.length -1]
    while(left < right) {
        let mid = left + Math.floor((right - left) / 2)
        if(rotateArray[mid] < rotateArray[right]) right = mid 
        else if(rotateArray[mid] > rotateArray[right])  left = mid + 1
        else right--
}
    return rotateArray[left]
}

module.exports = {
    minNumberInRotateArray : minNumberInRotateArray
};
