Hello @kushal1998,

Lets understand the sample test cases:
1
10111 10000

Explanation:

  1. first line contains number of test cases i.e. 1
  2. In each test case you have given 2 strings made of 0 and 1.
    a=10111 and b=10000
  3. You have to print a single string

Considerations:
if the ith index of a and b strings are different then append ‘1’ to the resultant string.
else append ‘0’ to it.

For above example:
index 0:
a=1 and b=1 (same)
so, c+= ‘0’; (‘0’)

index 1:
a=0 and b=0 (same)
so, c+= ‘0’; (‘00’)

index 2:
a=1 and b=0 (different)
so, c+=‘1’; (‘001’)

index 3:
a=1 and b=0 (different)
so, c+=‘1’; (‘0011’)

index 4:
a=1 and b=0 (different)
so, c+=‘1’; (‘00111’)

so, output is 00111

Hope, this would help.
