Swapping 2 Strings without Third variable - BenchResources.Net
Splet22. mar. 2024 · You can swap variables having integers without the use of additional memory (like a temporary array or variable). The following example swaps the variables a and b using the addition + and difference - arithmetic operators: let a = 1; let b = 2; a = a + b; b = a - b; a = a - b; console.log(a); console.log(b); Initially, a is 1 and b is 2. Splet12. jan. 2024 · Approach 2: Without using 3rd variable: Here we would be using an arithmetic operation to swap 2 values. Firstly, we add a + b to a (a would be greater than b as it is). Now we subtract b from a so the value of b is now available to b Now we subtract a with b again to a so a will have the value of B Syntax: a = a + b; b = a - b; a = a - b; Example: strawberry cider brands
Swap Two Strings in java without using third variable - YouTube
SpletTo swap two string variables without using third or temp variable, we use substring () method or replace () method of String class. substring () method has two overloaded forms :- 1) substring (int beginIndex) SpletThis program is to swap/exchange two numbers without using the third number in the way as given below: Example: Suppose, there are two numbers 25 and 23. Let X= 25 (First number), Y= 23 (second number) Swapping Logic: X = X + Y = 25 +23 = 48 Y = X - Y = 48 - 23 = 25 X = X -Y = 48 - 25 = 23 and the numbers are swapped as X =23 and Y =25.
