String Operations Count Program

[Priyanka94suthaar]

Given two strings str1 and str2 and below operations that can performed on str1. Insert, Remove and Replace operations can be performed on strings.

So we have to return true if change in operation like Insert/Remove/Replace is none or One step only.

For example below test cases should have this value :
System.out.println(isOneAway("abcde", "abcd")); // should return true (Only removing one char -e )
System.out.println(isOneAway("abde", "abcde")); // should return true (Only inserting one char - c)
System.out.println(isOneAway("a", "a")); // should return true (No change)
System.out.println(isOneAway("a", "b")); // should return true (Only replacing one char)
System.out.println(isOneAway("abcdef", "abqdef")); // should return true (Only replacing one char)
System.out.println(isOneAway("abcdef", "abccef")); // should return true (Only replacing one char)
System.out.println(isOneAway("abcdef", "abcde")); // should return true (Only inserting one char)
System.out.println(isOneAway("aaa", "abc")); // should return false beacuse its two character replace
System.out.println(isOneAway("abcde", "abc")); // should return false (Will require two operation to match)
System.out.println(isOneAway("abc", "abcde")); // should return false (Will require two operation to match)
System.out.println(isOneAway("abc", "bcc")); // should return false (Will require two operation to match)
