Hi Manan,
Take an input of t test cases. For each test case you need 2 string inputs say str1 and str2. Now make a stringbuilder ‘ans’. Since we have been given str1.length() == str2.length(), we traverse from for(i=0;i<str1.length();i++). If charAt(i) is same for both strings append 0 else append 1 to ‘ans’. And when the for loop breaks, print ‘ans’.
Also, please share your code so that I can suggest a better approach if possible.
