——————— can detect burst error of length less than or equal to degree of the polynomial and detects burst errors that affect odd number of bits.

An array A consists of n integers in locations A[0], A[1] ….A[n-1]. It is required to shift the elements of the array cyclically to the left by k places, where 1 <= k <= (n-1). An incomplete algorithm for doing this in linear time, without using another array is given below. Complete the algorithm by filling in the blanks.Assume all the variables are suitably declared.
min = n ; i = 0;
while (_______________) {
temp = A[i] ; j = i;
while ( __________ ) {
A[j] = ___________;
j= (j + k) mod n ;
If ( j< min ) then
min = j ;
}
A[ (n+ i – k) mod n ] = __________ ;
i= ________ ;
}
