I don't know technology, but using Satellite images, we are able to see that the continents once fitted into one 'jigsaw'. This shows that the continents must have drifted to its original place. Furthermore, Geothermal stations have pointed out convection currents in the Earth's mantle has caused the movement of crusts.

The input nums is supposed to be an array of unique integers ranging from 1 to nums.length (inclusive). However, there is a mist

The program is an illustration of loops.

Loops are used to perform repetitive and iterative operations.

The program in Python where comments are used to explain each line is as follows:

#This intializes the list

nums = [5,4,4,2,1]

#This gets the length of the list

size = len(nums)

#This iterates through the list

for i in range(size):

#The following if condition determines the repeating number

if nums[abs(nums[i])-1] > 0:

nums[abs(nums[i])-1] = -nums[abs(nums[i])-1]

else:

repeating = abs(nums[i])

#The following if condition determines the missing number

if nums[i]>0:

missing = i + 1

#This calculates and prints the sum of the missing and the repeating numbers
