How do you find the common elements in multiple arrays?
The elements which are common in all arrays can be checked by every() method and if the element of first array matches with all elements then that element is returned.
How to find common elements in three sorted arrays in Python?
A simple solution is to first find intersection of two arrays and store the intersection in a temporary array, then find the intersection of third array and temporary array. Time complexity of this solution is O(n1 + n2 + n3) where n1, n2 and n3 are sizes of ar1[], ar2[] and ar3[] respectively.
How to find common elements in three sorted array in C?
Declare an array of n3 size and take n3 elements from the user. Now, run a loop from i=0 to i=n1-1 and for every ar1[i] element we check if that i-th element present in second array if it is, Then check in third array, if element is found then print that element, Otherwise continue the checking for other elements.
