WebOct 18, 2024 · 1) Append second string to first string and store in first string: a = a + b 2) Call the Substring Method (int startIndex, int length) by passing startindex as 0 and length as, a.Length - b.Length: b = Substring (0, a.Length - b.Length); 3) Call the Substring Method (int startIndex) by passing startindex as b.Length as the argument to store the … WebIn this article, we will discuss how to swap two numbers without using a temp variable in C#. We can swap two numeric values (like int, float etc) without a temporary variable as follows : a = a + b ; b = a – b ; a = a – b ; We can also use XOR (^) operator for the same : a = a^b; b = b^a; a = a^b;

WebOct 15, 2024 · The number to the left of the E is the significand. The number to the right is the exponent, as a power of 10. Just like decimal numbers in math, doubles in C# can have rounding errors. Try this code: double third = 1.0 / 3.0; Console.WriteLine(third); You know that 0.3 repeating finite number of times isn't exactly the same as 1/3. Challenge WebOct 13, 2010 · Swap by XOR is not the only "creative" swapping algorithm possible. A similar result can be achieved by using arithmetic operations: void Swap ( ref int x, ref int y ) { x = x + y; y = x - y; x = x - y; } From a practical perspective, this is a technique that should be avoided in most cases.
WebSep 2, 2024 · We need to swap two sets of bits. XOR can be used in a similar way as it is used to swap 2 numbers. Following is the algorithm. 1) Move all bits of the first set to the rightmost side set1 = (x >> p1) & ((1U << n) - 1) Here the expression (1U << n) - 1 gives a number that contains last n bits set and other bits as 0. We do & with this ...
