Algorigthm for the above code
Algorithm: Shuffule Array and group its element
Input: Array, NumberOfGroups
Output: List of Groups with random values
1. Input Array from User
2. Input NumberOfGroups from user
2. Shuffle Array elements
for i = 0 to i < lenghOfArray
set randno = rand() % lenghOfArray
set randno1 = rand() % lenghOfArray
set temp = Array[randno ]
set Array[randno] = Array[randno1]
set Array[randno1] = temp
End of loop
3. set MinElementInRow = lenghOfArray div NumberOfGroups
4. set ExtraStd = lenghOfArray mod NumberOfGroups
5. set tempVar to 0
5. for i=0 to i < lenghtOfArray
if ExtraStd > 0 then
tempVar = MinElementInRow + 1
else
tempVar = MinElementInRow
for j=0 to j < tempVar AND i < lenghOfArray
print Array[i]
j++, i++
ExtraStd--
End of loop
6. return 0
