“Count Number of Vowels and Consonants in the String ” is a basic problem of string data structure. Here, we are given a string of length ‘n’ and our task is to count the number of vowels and consonants present in the string. Example: Input: Help12me!@study#bro Output: The number of...
“Count Frequency of Character in String” is a basic problem of string data structure. Here, we are given a string of length ‘n’ and our task is to write a program to count how many times a particular character occurs in the string. Example: Input: Enter a string: abcdrfedsdfddgr Enter...
“Count Number of characters of the character Array” is basically a problem of finding length of the character array. Here, we are given a character array and our task is to count the number of characters of the character array. The number of characters of the character array is same...
“Reverse a String” is a basic operation which can be applied over string. Here, we are given a string of length ‘n’ and our task is to write a program to reverse the given string without using in-built function. Example: INPUT: ABCDEFGH OUTPUT: HGFEDCBA There are multiple ways to reverse a...
“Print Matrix in Spiral Order” is a standard interview problem based on matrix data structure which have been asked in many technical and algorithmic interviews. Here, we are given a matrix of size N*M and our task is to print the following matrix in spiral Order. Example: INPUT: N=3, M=3...
“Print Matrix in zig-zag order” is a a problem of printing the given matrix of size N*M in zig-zag order. The zig-zag order of the matrix is traversing the first row of matrix from left to right, next row from right to left, next row from left to right and so...
