Follow the steps below to solve this problem: Initialize a vector freq [] of size 256 with values 0 to store the frequency of each character of the string. Iterate over the range [0, N) using the variable i and increase the count of s [i] in the array freq [] by 1.

WebJan 16, 2024 · It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell compiler. Example : 0x6400 translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600. When compiler reads 0x6400, It understands the number is hexadecimal with the help of 0x term. WebIn computer architecture, 256-bit integers, memory addresses, or other data units are those that are 256 bits (32 octets) wide. Also, 256-bit central processing unit (CPU) and …
